I cannot speak to your private examples, but I think you may be reading that into what Politzer said.
Not me. This tip-off story had been talked about in the community for a long time, just never publicly until Politzer decided to carefully and tactfully state what he knew personally and avoid speculating on what might have transpired. The result itself, of course, was ripe for discovery, and indeed was discovered but glossed over by others before him. I mentioned this particular story because it's one of the most famous and most public ones. Of course, it might all be rumors and in reality there was no issue.
'When you hear hoofbeats, think horses, not zebras'. I see here by Politzer's testimony a multiple discovery of at least 3 (Gell-Mann and the more-than-one persons implied by 'several') and you ask me to believe that a fourth multiple is not yet another multiple but rather a plagiarism/theft based, solely on you say it was being talked about. It's not exactly a convincing case.

A few notes about the community
If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.
A list of some posts that are pretty awesome
I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:
More suggestions are welcome! Or just check out the top-rated posts from the history of Less Wrong. Most posts at +50 or more are well worth your time.
Welcome to Less Wrong, and we look forward to hearing from you throughout the site!
