Ask Absolutely! since she is our wannabe mod... She says there are no IP bans.
What forum would work without IP bans??? Of course they exist....
I've been there with my own members and cannot say of course why it happens HERE for you, but if you have a flexible IP you could sort of end up on one someone else got on a blacklist. IF that would be the case, you could go to that blacklist and try to clear your "name".
Last week a content delivery network (CDN) was setup to handle the images for the forum. This off loads having to process the images to another server, leaving the main server to handle mostly database request.
For some reason this has made everyones ip address look like it coming from the same network.
The blocked ips from that network have been removed from the list.
