Will my Twitch or Riot accounts be flagged as a bot if I have created several?

I've created several acc that run on different browsers at the same time.

Could it be that I can't get a key that you think my accounts are bots?

No they won't.

As long as you don't use bots to level if you are unlucky all will be blocked when using bots…

Usually, every 2 accounts are enough, why several?
