In the last time Don't Starve Together massively experiences people with multiple accounts (4 confirmed, probably more) roaming from one server to the other just vote-kicking people.
Confirmed through many experiences are:

"Clouds" was also able to rejoin again after successfully being kicked (in between their continuing vote-kicks), so maybe there's a possibility to still rejoin after being kicked or there is yet another account with the same name.
This spoils the game for everybody on Klei Official Servers as well as other dedicated servers.
