Most probably device ban(nig) is in full swing now that doxx effects have started to factor in.
My solution would be to take a friends phone for an hour, go to incognito/download a bunch of new browsers, make a new account in each browser (no cookie problem)
Jot them down.
Come back to your old phone. Download a new browser, make a new comment and see if you can view the upvotes. Theoretically it should device ban both you and your phones but Idk if device banning works simultaneously in more than one devices.
