Not exactly a time expiration as polo said, but the nature of the warnings and history are taken into consideration. A spammer wouldn't make it to his second strike, for instance. We're very happy to be lenient, the more folks around the merrier! But when it's given, you gotta redeem that for us, please.
Being a problem causer after repeated extra chances is the easiest way to get the permanent axe. And I hate to see that happen, you guys :\
For those of you on iPhone/Safari -- the 'Full Version' problem seems to be a Safari-only issue, but I'm not sure. Is this happening on other boards that use Invision? For example, try http://community.invisionpower.com/
I logged on to HB using Safari on my iPhone today and the full site loaded just fine. I'm not disputing that other people are having problems, I'm sure they are...but I'm not, at least not with my iPhone but my iPad is a completely different story.
iPad+Safari+Huskerboard=death. It loads an indecipherably broken version of the site over half the time. I've tried clearing the browser out, reseting everything and all that jazz but nothing fixes it. Other browsers load HB just fine on my iPad though, it's just a Safari issue.
