Has Fluther ever had a problem with Trolls?

TROLL
1a. Noun
One who posts a deliberately provocative message to a newsgroup or message board with the intention of causing maximum disruption and argument.

1b. Noun
A person who, on a message forum of some type, attacks and flames other members of the forum for any of a number of reasons such as rank, previous disagreements, sex, status, ect.
A troll usually flames threads without staying on topic, unlike a “Flamer” who flames a thread because he/she disagrees with the content of the thread.

1c. Noun
A member of an internet forum who continually harangues and harasses others. Someone with nothing worthwhile to add to a certain conversation, but rather continually threadjacks or changes the subject, as well as thinks every member of the forum is talking about them and only them. Trolls often go by multiple names to circumvent getting banned.

Do you know anyone on here/has been on here that fits that description?

I’m a member of a few sites that have been attacked recently. What is your favourite way of dealing with them?
I’m a mod on my favourite site and I love to just wade in and delete all comments from them.

I understand that just ignoring them and rising above them is the best option but it is far from the most interesting!
