There’s some truth to the concern, but it’s been a bit overstated. Quickly opening dozens of tabs could be is among many other nuances our system checks for.
Users whose behavior might trigger our system are usually just asked to stop opening so many tabs at once after a manual review from our side. If you’ve never received such a request, there’s nothing to worry about
I never thought much about this because my outdated old phone would open neither streams nor forum, but now I finally got myself a new one. And I see that there is something to be said for having your favorite girl on the big screen while browsing the forum, or checking for interesting activity in other realms, on the phone. So, to make this clear, is it allowed to open streams on two devices simultaneously (if not done excessively, I’m not talking about multiple tabs) or could it get me banned?
