That's because people don't give rep when you rep, they give rep when they feel you deserve it.
Not that you don't, just some people haven't noticed that you do. I will rep you if you ask me, if it'll make you happy, but since rep is basically an ego-inflating version of 'like' where people can troll-neg you, I find no point in rep.
BL got 10 points for an alt about a month ago so he was already close to a ban. he probably was banned for something trivial. you answered your question about CyberCubed, he was trolling PAD. Robert wouldn't stop complaining about the new rep feature, and Tropius19 was probably banned for something trivial]
[lol you should have been around when rilla was trolling sppf with all his alts-- he's actually another member called Fatal]
