contrary to your belief the very latest stock version of phpbb gets hacked, allot.
Nope. I've been working with phpBB for about 4-5 years, all forums that I've seen being hacked are ones using phpBB 2.0.12 or older version. Unlike you, I'm not just another phpBB user, I'm designing styles and writing mods for it, and I have lots of clients so I do know what is and what isn't getting hacked.
Please stop spreading baseless rumors. If you are saying latest phpBB is getting hacked, provide a proof (point to a forum that is hacked, or exploit, or any other reliable proof, not to some newbie forum admin's clueless post), which you can't do.
