Help!

Hey guys, is there any way I could find someone? All I know about them is that their ign is Gavinmalachi, thats right I remember it from 4 years ago... we were pretty much best friends. We played with each other every day of every week of every month. We were best friends. Until the server we played on (the only way we talked to each other) went down, it is back up now and I have been checking every day from the past 2 years and he has never been on. Can I please have help finding him? Please?
P.S. no player finding websites work :/
