Halp, can't block all the bots. T_T

Supporting this one - There is no reason this should be capped.
I have only seen (and blocked) three gold-sellers though

I have run in to that on the Gunma server as well.  Too many spambots in the region chat for be to block them all.  Unfortunately, that means the only way for me to stop enough of the spam to get a usable chat was to turn of Region chat completely.  I do wish there was a better solution.

It's a big issue in the french server Hogdonny! There's a spam bot on "region", "faction" and "party finder" !!! I can't be expected to not have any channel active in an mmo right?!

I just left the chat channels that are spammed the worse, only channels I have now are says and clan chat.
