In internet forums, the host sometimes has the power to lock threads in which members do not follow the rules. When locked, the user is un-able to post on the thread anymore. Sometimes they might make alternate accounts to continue breaking rules, and in this case, the IP address may be banned from connecting to the server.
Banning (sometimes called 'blocking' or 'permabanning') is commonplace in internet culture. The "dread Kenny", or "Sponis" are mythical creatures used in many of these forums to enforce locking of threads and banning of members.
MSN spammers, beware...
