Any word on whether or not this change is permanent? On dozens of occassions before I've tried to connect to freenode with mibbit only to find that it had been blocked for a few days. I suspect it's a spam management tecnique whereby they probably (maybe even correctly) estimate that like 5% of the people using mibbit are legitimately chatting, and the rest are evading bans (common in #68kMLA unfortunately) or otherwise spamming.
