Doesn't/wouldn't work. They can already do that but as long as something can be put in their signature ICO crap campaigns can and will pay them for it. We need to force their hand by removing it completely so nothing can be put there so there's nothing for them to be paid for. Juniors can't even have a link in their sig but Junior accounts are being farmed in their thousands to take advantage that campaigns will pay them for any spam they can be bothered to make (or copy and paste). I do hope theymos will remove their signatures at some point because it effects their ability to post zero and they can still purchase a Copper Membership to get a Member-level signature anyway, but I would argue Copper should just include some basic whitelisting features because it's too cheap as it is. We could introduce Silver and Gold ranks that are more expensive and include Full/Hero-member benefits instead.
