I don't think that it should be bannable. I think that it's a part of factions, and people who experience it, probably won't ever fall for it again. It is something that has been with factions for a while (since its release, which isn't a long time ago), and most people know better than to fall for tp traps. If you really think it should be bannable, I'd recommend making a suggestion here as well suggestions.manacube.com . The top posts get added in. Hope this helps!
