Administrators I believe can block/ban specific users for a number of issues, as well as request a global Wiki-wide ban should their behavior prove one necessary. As well as that, I believe administrators also have the power to delete comments made by others, though I'm not sure if they're being put to use - I only have experience of that on other wikis.

Nevertheless, the message you're conveying is so true - there are people out there that simply want to bring everything you do down.
