I propose an unconditional, unlimited ban for everbody having a bitcoin address in their signature!
Here it gets ridiculous.
Like, seriously, ridiculous. Ban someone for a bitcoin address in their forum signature? What's next? Ban people for having a megahash/sec tag? Ban people for saying something about Satoshi? Ban people for linking to their Bitcoin-related service without having a 'premium' forum subscription (as some non-Bitcoin forums do)?
Since you obviously didn't read this thread, but for some reason insist on commenting anyway, I will hint you to my previous post:
Of course I wasn't seriously proposing to put a rule in place. Also, I see why people providing an actual service would ask for donations.
I personally just don't think coming off all begging is worth the 22 Cents a month.
