I have been told by another member that whilst accidentally trying to upload a picture that was too large he was banned for life as it was deemed to be a "DOS attack". This seems a bit unfair for a simple mistake
Slight exaggeration I think

The site does have some detection systems in place to prevent things like DOS attacks etc from hackers etc. (And believe me they do try on a regular basis...

). Suspect the member concerned got incorrectly stopped. However, when this happens it's usually only a automatic temporary block of a few hours. It certainly isn't a "life ban".
In general it can happen if accessing from a mobile phone as the browsers tend to badly configured. iPhones are the worse culprits.
If you pm me the details of the member I'd be more than happy to check it out.
Obviously if the site was seriously hacked then it'll more of a problem, so we need something in place but I accept that occasionally it might mess up
