Add to Blacklist = Option to report for gil selling

Can we have this? If you blacklist someone, you should have a window come up immediately after you confirm that you want to add them to the blacklist with the following...

Do you want to report this user?
[drop down menu]
Gil Selling
Abuse
Cheating
Other

[Notes entry area: optional unless you select Other]

[Yes Button] [No Button]

I don't bother to report spammers at the moment, but this kind of automated system would mean gil sellers etc. would be spotted a lot faster.

EDIT: I don't know if it's possible, but you could also set it up so that it automatically detects the last five lines of text sent to you from that user or something similar.
