Do you think any wrestlers would wrestle for free?

I know that some people, like the janitors of 4chan, do it for free, but would any wrestler be stupid enough to do it?

Just think about it, you are basically reduced to a cuckold slave, not even a prostitute because those get paid to get fucked, more like a sex slave. What integrity do you have as a man if you allow someone to take advance of your services without you getting anything in return, you know?

Who would work essentially a full time job for free and get no respect for it?
