So he felt bad cos u lied to someone & hosted adult sites. Anyways, we all learn from our mistakes & I believe you wont be ever hacked again (you know not to be stupid now). You can ask your hosting company... how this person was able to access your files. My brother's site was hacked and now he makes sure he dosent go for cheap unsecured hosting. Now security is his prime concern before chosing a host.
Yeah, I seriously think it is time for you to change web hosts - the server you are hosted on probably has some sort of exploit or bug that the hacker can continue to take advantage of. Also have a look at microsofts page on creating secure passwords, never ever store passwords on a remote machine, I memorize all mine but if you must you can write it down with a pen & paper. You should really read up on basic online security.
Actually the adult sites wasnt mine and i didnt lied with him I'mm taking legal action against him since i got his adress He is from My city Saad
