Excimer is a troll and liar, who is only out for negative feedbacks and lies, not to be trusted.
Do you think he'd give two shits about your rants and calls for neg tags? How many tags do you think can keep a troll at bay? He's already been tagged, 9 if I'm not mistaken, so one more won't make any difference. You'd only be giving attention to a matter that is of no consequence.
So what if you think he's a liar and untrustworthy, don't you think it will be for the best if you don't have any business with him since doing so will only mean you're blind and I don't think any ones pays the dude some mind more than I'd necessary so I'd advice you to do the same. Better yet, you can put him on
Ignore if his presence bothers you too much.
