I believe I recall seeing some false statements in this thread I'd like to address. With regards to MFC, it's true models and members (w 1,000 points) can change their names, however those name changes are normally reflected on profiles (throughout the site actually) within seconds. So comments potentially can be persistent with regards to the correct individuals. The problem though, is that both models and members can selectively delete comments or turn off/hide comments altogether. This is one reason the MFC comment system is useless.
Another is that it's open to abuse by malicious models and members alike, which is why in another thread I suggested comments ought to be linked to registered/verified transactions.
