It's ironic isn't it?? If you're the one doing the glitching it's great, if someone else is, they're proper slags for doing it. Same as getting the dogs, anyone else's are annoying little buggers, when they're yours, they're smashing.
I glitched a couple of times when I first started, absolutley just for the laugh of it, just to hear people saying 'Wha'?? Where the hell is he??' etc. Which is how I ended up here. However, I think if people like to do it, then it's up to them, I won't judge them for it. It can also be beneficial, as if I can see people practicing that Dark Art then I know for sure where some of the oppo are and avoid that area, similarily I can also practice that other Dark Art, camping, and slot anyone trying to get back in or out of the glitch.
It all adds to the general fabric of the game, so accept the challenge that glitching brings and enjoy yourself.
