I've whitelisted
over 200 users who ran into a proxyban. When I approve them, I email them this:
I don't know how many people read the rules from this link, but so far, only 1% of them has been banned.
@theymos: have you considered actmyname's suggestion?
can you make the default signature link to the forum rule thread?
I like it! How about doing this only for the first 7 days for new accounts or the first 5 posts (whatever comes first)? Copper Members should of course be able to instantly change it.
If each Newbie has a signature saying "Welcome to Bitcointalk! Please check the rules a bit:
https://bitcointalk.org/index.php?topic=703657.0 ", that would give massive exposure to the rules in the threads where Newbies
post spam the most.
