They were wrong. There's been another thread about this and all us students who are actually at Lancaster were a tad bewildered by it. There's actually a campaign going on to attack that board, hahaha. Anyway, if the locals hate the students then I certainly haven't been witness to it and I wouldn't imagine it's any worse than every other uni in the country. As for the suicides, well it's hardly a regular occurence. It's not like every day someone throws themselves off the tower!
Hope that helped in some way. Don't judge a whole university based on one apparently very bitter persons opinions.
