M+ tanks asking for gold to tank

Was putting together some M+3 last night and group was filling fast. Had a prot pally 652 join and pm “ill only tank for 20k gold or no go” this gigaloser though he was worth anything other then an invite. Put this shit stain on blast in group chat and he had audacity to call us losers when everyone told him to kick rocks before I kicked him.

Thoughts on this and if this is going to be the new norm?
