As far as I'm concerned, if someone has been found not guilty, then they are not guilty. There are some who say that this man's life has been ruined. I am not sure that it has. The who 'smoke without fire' brigade should be ignored. He has been found not guilty, and that should be that.
By the way - anonymity for defendants in rape and sexual abuse trials is not such a good idea.
Operation Yewtree has shown us that abusers don't just do it once...there is always a pattern of abuse. You keep names secret, and the opportunity to discover that pattern is lost.
