How to report someone

[Nagash]

After a few months playing on P99, I eventually got someone on my ignore list. However, I don't believe this is enough. I logged in today with my druid camped in the EC Tunnel, gate to WC and receive a tell from this random bloke "Fk u fag". No reason to the insult that I can think of. Tried to talk to him to understand, nothing then I eventually receive an answer along the line of "grow up or get some respect" (I got the screenshots of the whole thing). I won't name this person on the forum out of courtesy (although I'm not sure why I show some sourtesy to a dickhead like that) but I'd very much like being able to contact one of the dev/GM to provide them the screenies and let them do their do. How do I do that? Thank you.

Kind regards,
Nagash
