ULPT request: any alternative to stdcheck.com?

Nobody cheated or anything, and he was the one to end things. One of the dumb things he’s been doing is talking about being a MILF hunter with friends and he just needs to be knocked down. I know I can send email but would the “milfs” really have his email addresss? I want it to be believable
