multiple accounts on one device - still threat shadowban?

So Ive read here many times that multiple accounts on one device leads to shadowban.

Few updates ago TikTok give us ability to link few accounts that you can easly change them without logging out.
So... why would they shadowban for using more than one acc? Seems unlogical

Anybody got update about this situation?

the problem isn't with connecting multiple accounts if one of them has a problem the rest are involved somehow

Like he said^ it isn't the multiple accounts that causes the problem. Just the "contagiousness" of shadowbans etc

One thing I can tell you for sure, if you have multiple accounts on one IP, if one account gets shadow banned , others will also get banned.
