So It's against the rules to need for another job?....

The thing about reporting harassment/cheating in a roulette group (and I'm speaking from experience here) is the GMs seem to have a hard time unless you can:

a.) give them exact times (always always have timestamps turned on in your chat logs)
b.) go on the lodestone to look up what server the people in your group were from (can be tough if someone's using a common name)
c.) paste chat log snippets in your ticket so the GMs can search the logs for exact text strings.

The GMs in my experience have been very appreciative when I give them a lot more information than I think they need. I still can't tell you whether anything ever came of either of the two non-RMT GM reports I've filed, but there it is.
