The most logical reason behind the delay of emails being sent is that the server's mail queue is backed up by the thousands (likely tens of thousands) of emails sent out every day. However, I have not yet confirmed that. I will look into it now though.
They may be censoring emails, Pms, ect. Trying to prevent people from getting information from each other in case someone tries to start another forum because of all the crap that is going on here. This seemed to happen about the time the banner went up.
Lol... that is completely an untrue accusation, and honestly, I don't believe it is even possible to censor emails, PMs, etc. before they are sent. If it is possible, I can assure you the amount of work it would take to do something like that would far outweigh any benefits anyone could hope to gain by doing such a thing.
And if the account is about to be shut down then there's no incentive for the server folks to fix it here.
That is another false accusation. The account, or server, isn't going to be shut down, and if it is, it will only be taken offline for 24-30 hours at the most. There are plenty of incentives to look into this, I can assure you of that.
