Guilds - some very old guilds have Bedrock players with a Period prefix

This is probably not a new issue, and I'm honestly unsure if it should be considered a bug, though I could imagine it causing issues if these players did return. I don't think this is too widespread, but it may affect a small number of old guilds. An example of this is the guild "Alts". I think this is the result of the Minehut proxy. At one point you could join OGN via Minehut. Players that joined via Minehut would have a period prefix instead of the typical star prefix. The concern is if the system literally sees these as different players than if the same Bedrock player joined through the regular IP. To my knowledge the Minehut proxy hasn't existed for a while, so there's no way to join with the period prefix anymore. See screenshot
