I can't speak for all of them but I believe that this kind of people are after the quick bucks instead of long-term money especially in this forum, we just have to understand that not everyone likes to post in a forum about stuff related to the theme of the forum everytime.
They wouldn't hang around for close to four years and make over a thousand posts if they planned to make away with just over a hundred bucks.
Dude, people change, didn't you get the memo? Just because someone's been trustworthy for years on doesn't mean that that person won't flip on you. Everyone's got a price and that person decided that he doesn't want to be on this forum anymore so getting something little out might not be a bad idea or I'm overthinking it and that person died and we all know a dead man can't pay no debts.
