Models. You need to realize this right now. ANY time you put something on the internet, it is there FOREVER. It can never be eliminated, and eventually it will be found by someone who you'd rather not find it.
For example, any time you are on cam, you should assume that images or videos of that cam show will be recorded and put on the internet forever. I'm talking private shows, group shows, and ESPECIALLY public shows. It's already the case that MFC owns the rights to all of said imagery and video, and can do with it what they like.
You may not like it when members record your shows and upload them to different places on the internet, and you can try hard to get those images taken down. Sometimes you may find that you are even successful with getting an instance of something taken down. But the truth is, once it's out there it is impossible to fully retract. All it takes is one person to have saved a copy of it before it got taken down, and it can be reposted again. There is jack shit you can do about it, so it is not worth your time trying to take it down. It will only delay the inevitable, and could in fact speed it up by pissing people off and making them post it more.
A lot of models use location-block in order to block people from their hometown and surrounding area from seeing them. This is a decent short-term solution, but in the end, it's pointless. There is absolutely no way to guarantee that people from your home town will never find out. All it takes is one time for someone you know from real life to be travelling out of state and see you online, or see your pictures. It is also easy for technically-savvy people to use a proxy to get around location blocks. The point is, location block is only a temporary solution, and there are ways around it. You will be found out. It is only a matter of time.
Let's say you're super lucky, and during your several-year stint as a camwhore, you are never found by someone you know in real life. You think you're off the hook? Along with all the imagery MFC has recorded of you and could sell at any point in time, you can bet that random members (and guests!) have taken lots of imagery too. It will be on the internet forever. 40 years down the road, your kids will stumble across naked pictures and videos of you on the internet. It's going to happen. This is reality, and there is nothing you can do to change it.
The point? If you don't want your friends and family to find out you're a camwhore, then don't become a camwhore. Don't want your grandkids to see videos of you anally fisting yourself? Then don't become a camwhore. Don't want the local authorities to find out you're a camwhore? I think I'm becoming redundant here.
Do you think your real-life identity is secret? All it takes is ONE person you know from real life to find you on MFC and leak your identity. It's going to happen eventually. Hopefully it won't happen for a while, but you need to be prepared for the day when it does happen, because mark my words, it will.
Once something is on the internet, it is there forever. Making an attempt to change that fact only makes you look stupid.
