I challenge you to crash the server. The best you could do is lag it, but I have already gotten rid of several bot spammers and have heavily restricted what things you can WorldEdit. Good luck!

You will want to blacklist certain blocks, like chests and pressure plates, from the WorldEdit plugin. While it may not be possible to crash the server, it is certainly possible (and very easy) to make the server practically unplayable for those who have just spawned in.
