Edited to add my third answer
Partial Answer (But this time I am fairly sure that I got it)
I think the answer is
He's Lyndon B. Johnson, and he is looking for a manager for his 1964 Presidential Election campaign.
How I came to this answer:
1.
After it became clear that dropmail.me didn't exist at the time of the ad, we can safely assume that the choice of lj36 as a "username" is deliberate. Lyndon Johnson is the 36th President of the United States. Actually, since he assumed presidency after the assassination of JFK, he was already the 36th President during the campaign.
Some comments regarding the email address
I think it isn't an email address, because a) email was not in wide use at that time b) the phrasing of the ad "Leave a message on ...": One would use "Send a mail to" or something like that. I'd speculate that it could be a special place for the applicants to leave an actual message.
2.
"Handler": "a manager of a political or public figure or campaign" This should be pretty self-explanatory.
3.
"Purple (Cows)". The states where the Republican and Democrat votes are close to each other are sometimes called "Purple States". Because of the winner-takes-all election system in most states, and a good strategy for a presidential candidate would be to try to win these states.
Some comments regarding the phone number:
The phone number is formatted really weird, and has the same formatting (and the digit/letter count) as "(LJ)FOR-PRESIDENT" but I don't know how to transform the number into that, I tried a couple of ROT ciphers but couldn't get anything.
I couldn't make use of these, but they might be (and probably are) clues as well:
- Farm
- dropmail.me
- The phone number
Edited to add my new answer
Partial (and probably incorrect) answer
This was my second attempt, and it was wrong. But I am keeping it for the same reasons that I'm keeping my first attempt: Every wrong answer is a step closer to the right answer.
After Hints 5&6, I no longer have a clear idea what the answer is, however I found a bunch of things that could be useful. I was able to use some of the clues that I couldn't use in my previous answer, but now I don't have any idea on how to use the seemingly most important clue.
Things I learned after Hints 5&6 came and I'll use in my explanations:
WWW was invented in 1989, this means
dropmail.me surely didn't exist at the time of this article. (Hint 5)
Phone numbers were first used in 1879, this means
The phone number is actually a phone number (Hint 6)
dropmail.me does not have a fixed expiry time (it is deleted when you close your tab instead of some fixed time after you create it), this means
My conclusion about the usage of dropmail.me implies an urgent job (in my previous answer) is COMPLETELY FALSE. And I think one can exploit this feature of dropmail.me to mail to the future (This might be important when I get closer to the full answer)
(I can elaborate on why I think this can happen if people ask me in the comments.)
Now to what I think is going on:
Definitely some sort of time travelling. I immediately realized this after Hint 5 came.
My reasoning, and some conclusions:
1.
The first bullet point implies that the person must be from the future. I don't see a clear motivation for someone from the future to put an ad on the newspaper. However, I have a couple of possible explanations, and I'll write them to the end of the answer.
2.
The phone number looks a bit too long for a phone number from our time. I think this might be a consequence of increased population in the future and not enough phone numbers for the people so they put more digits in them. I don't think the phone number is a cipher.
3.
dropmail.me gives the mail addresses completely random (as far as I could understand), and lj36 can't be the deliberate choice of the person. However, considering that short addresses must all have been deleted by now, so the person shouldn't have closed their tab in decades.
Some possible explanations of what might have happened:
1.
Person A and person B exists. One of them (B) travels to the past. He doesn't come back for quite a while so A becomes worried and puts this ad to the newspaper, hoping that B sees it and mails him when dropmail.me is launched. (Actually B will have already mailed him since he is in the past)
2.
Person A and person B exists. One of them (B) travels to the future. B comes back, with the knowledge that dropmail.me will have launched in the future, and he has the [email protected] address. Then A travels to the future, but he doesn't come back for quite a while so B becomes worried and puts this ad on the newspaper, hoping that A sees it and somehow gets back (Since you can mail to the future but not the past, he can't expect A to reply to his mail)
I think other possible explanations can be made, but these are coming to my mind right now; I may edit to add more possible explanations later.
I could not make use of these, but they might be (and probably are) clues as well:
- Purple cows (This is probably the most important clue and might cause my answer to fall apart.)
- Farm
- The phone number might be a cipher but I don't think it is
- 10 clues.
- lj36 might be a clue but I don't think so because of my 3rd conclusion.
My old and wrong answer
This answer is incorrect, but I am leaving this here for other people to see another incorrect answer: Every wrong answer is a step closer to the right answer.
I think the answer is
The person is a human trafficker. This ad is a message to the person whom he is sending the people.
My reasoning for this:
1.
LJ36 is a plane. Because of this I thought the person could be transferring something.
2.
dropmail.me is a temporary email provider. This means the whatever the person is doing, it is very urgent, because temporary emails are deleted after use.
3.
The OP said the person does not work with computers, and his job is more interesting than a server farm. Illegal stuff can be interesting to the people who do them.
4.
The OP also said (Under the answer "gambling") abstractions are needed but not in that direction. I made abstractions in another direction.
5.
This is probably the most important one.
The purple cows. Purple is associated with women. Cows give milk. Milk come from breasts. If you think a bit, sex workers are kind of paid for for their breasts.
I could not make use of these, but they might be (and probably are) clues as well:
- The phone number
- "farm"
- The fact that there are 10 clues. That is almost as much as the words in the ad.
- The "kind" of help. How can "help" even have kinds?
