WRONG...it has to do with the security of the software because the same people responsible for securing their website are responsible for securing phpbb. Not only were they completely compromised but it took them some time to actually regain their site. 48 hours max should have been more than enough to rebuild and return from a backup. And add Mybb to the poll...it's the only software I use after ditching phpbb and VB.
I love fluxbb, its nice forum software with ease of use and pretty much faster than any other forum software.
There are actually more than 20 forum softwares, we don't know about many of them See the list of forum softwares here
