Although unnecessary when reporting servers, I find it useful to sometimes, while recording, try to clear up what was going on with the admin. That first mass boot seemed like obvious abuse, but there might have been cause for it, and the last one may have been related to your leaving and entering the server multiple times in the span of a few minutes. It's still against the rules for them to kick players for these reasons, but never attribute to malice that which is adequately explained by stupidity. It may be that a reminder of the server hosting rules could keep him from repeating any mistakes. Of course, if he continues to kick you or bans you for bringing up a valid concern, you can then submit that here as evidence of abuse. It also helps to get multiple videos, separated by ten to fifteen minutes, that clearly show everyone in the lobby except the same group of players being dropped from the server. This helps in identifying obvious abuse. This isn't always possible and you should try to secure two such videos back to back if dealing with especially aggressive admins.
