I never hacked but my friend's community portal recently hacked the main page. He says this may hacked by his programmer due to some payment issue. I'm the first realize it and told my friend. Problem fixed within 24hours.
This is just hibidy hobidy non sense 1. Hackers will always try to ruin sites 2. You need backups.. Get those 2 through yur' skull and you'll do fine. I have like 3 servers just for backups lol
