Why charge them more? I'd much rather see those who do not disclose and are found out be banned forever. I know that's a bit tricky but losing your alias, membermarks and what not takes away a bit of the "legitimacy" they now have. I don't have a problem at all with folks who disclose. Perhaps you could put shakerzzz in charge of ferreting out those who don't, he seems to be pretty adamant about smacking them when he can. Just a thought :)
