feeling like committing suicide for the situation I am facing right now. It is kind of feeling like betrayed due to heavy jealous, that too from a colleague.
I have some sympathy for you, but being suicidal about being banned from a discussion forum is a bit over the top. Nobody ought to be this dependent on signature campaigns for their living, because they could easily become a thing of the past. Look at how few of them there are now compared to 2015. What would you do if the campaign you were in suddenly just ended?
I wouldn't ridicule a member like you, because you're not the typical shitposting noob who gets caught for plagiarism, but buying posts is never a good idea, nor is giving someone else access to your account. In the end, you're the one who's responsible for the ban. Just calm down, take a few deep breaths, and think of a way to go on living.
You have a very unique excuse for your ban but I don't think you being not the one who posted the plagiarized post/s can help you save your account. Sad to see your account go
The excuse isn't unique; I've heard it before, and it certainly could be true. But it doesn't matter in the end, because the rules about copy/pasting are enforced pretty much without prejudice or preference. I'd also add that I'm not exactly sad about him getting banned, but it is indeed unfortunate and I do feel bad for him.
