No, I don't think they are the same person. Father Time, if he is who he's been identified as on this thread, had numerous web names on another site. He would use them mostly to shill incessantly for one or two prep players. He would generally use one name until he pushed the envelope too far with the webmasters, then disappear for a little bit and reincarnate himself under a new moniker, but the message never changed, so you knew it was him.
XMLB frequented the same site. He didn't seem to be as bad. He would trumpet some kids, but it never appeared he had nearly the same agenda as Father Time. He certainly mentioned lots of players across the nation for someone who did not do this for a living. Whether he saw all the kids he wrote about, I can't say, but I think we'd all love to have that much free time to watch baseball.
