I have alts. No automatic sync, but you can list your alts in your profile like I do.
On mobile make sure to use a client which makes it easy to switch between accounts (I use Thunder, which additionally shows server status in the account switcher!)
Addendum: Yes we know that you think ml/hexbear/grad are tankies and or .world are a bunch of liberals but it gets old quickly. Try and come up with new material.
