I've seen a few posts that have been new info to me today. Those particular posts had comments about it being old news. Berating the poster. Basically trying to make the OP look or feel stupid. Just because you know info doesn't mean everyone else does. Posts move along quickly and are easily missed. I'm on here several times a day and i miss tons of posts. Sure, if it's incorrect lets fix that, hell that can even be done politely. If you know, don't be an ass, just move on.
Perhaps this is the new liberal shill tactic! Make posters feel stupid so they fear posting again. Seems like a libtard thing to do. Damn we need more golden rule in the world!
I'll step off my soap box now. Cue libtard attacks....
The board is under constant attacks from sock puppets and bots who aim to to disrupt, divide and demoralize us. They also want to make us look bad by posting idiotic, racist or violent things and then upvoting others like them doing the same.
After a while you learn to just read around it. Report those who are.doing it if you want. It helps the mods a little but this can never be eradicated fully until the cabal is eradicated fully.
