Hello,
someone using account "NoRx" is advertising for some private dota league website. He's using some kind of bot which whispers to EVERY player that joins to CZ/SK channel. The bot whispers repeatedly after each rejoin, so it becomes very annoying after some time.

5. Any links or information advertising to other websites or servers is forbidden and may lead to punishment and permanent ban from the server and/or forum.
I didn't find any proper section to report advertising so i post it here.
