I can't comment on Wordpress blogs. I had a Wordpress account, lo! these many years ago, and my email address seems inexorably tied to this account. Without this password, Wordpress will not allow me to comment on any Wordpress blogs. There appears to be no easy way to either reset my long-forgotten password or delete my account.
Please don't give me advice on how to fix the problem. This is not the sort of problem that should require advice to fix.
