Does SW ban users?

Why... What are you planning?

Three warnings = a account ban.
Three account bans = a device ban.

They no longer need to do IP bans. And are able to figure out if you're using VPN.

And they can figure out if you have more than the max three accounts.

There is a way to avoid all of that. Yet I won't give the details! It's not obvious though.

This is an unending game. As soon as one technology is figured out another technology comes in.

My experience is that SW will try not to ban people on the basis that they'll just come back anyway on other accounts or they'll use other means by which to evade IP bans. So basically if you're being harassed by someone who keeps making alt accounts to evade blocks then you might as well just leave yourself, or contact local law enforcement if the activity constitutes a crime. It's all on you though.

Ahh yes, the user who wants to get banned. Strange goals.

depends on who you know and who you are

I just banned YOU

If they ban the IP address of a public library or Internet cafe, they would be banning hundreds of innocent people who created their accounts on those premises, wouldn't they? That would be stupid as well as unfair and unrealistic.

If you make too many accounts they become ghosted where no one can see you it's based on wifi that you're connected to and your phone's IMEI number I'm sure they have ways to block a certain computer too if they wanted to

Yes, one example is for someone who's had too many accounts.

A few but it should ban more
