Oh yeah...if somebody good wants in...they can find a way for sure. But most GOOD hosting companies have guys who make sure your shit is secure (not talking about shit hosting).
Nobody wants a box hacked inside their network. It opens up the whole network to a possible problem.
Bottom line is it's up to you to get in touch with your hosting company and do everything you can to tighten up security and close any backdoors that might be open.
But again...most email lists are for sale by the program owners anyway. That used to be kinda valuable.
These days? Not so much. Everybody knows the handful of affiliates left with any traffic and ability to send sales. The tens of thousands of others are practically useless. lol
Hell, I used to be able to send a lot of traffic and sales. Spam me these days and get my info and I sign up...it ain't a big deal.
You probably won't get shit for sales from me. And whatever company did it probably already has their content stolen and on every pirate site in the world for free anyway, making my job as an affiliate even harder.
Who really knows what the real story is. As I said, why go to the trouble of hacking when you can just buy the damn list for cheap. And even then, it isn't worth much.
Is Freeones an affiliate? Check.
Are you working social networks? Check.
Viral marketing. Check.
That pretty much covers it in 2012 unfortunately for paysite owners.
