So I tried signing up for Twitter to do a little trolling there... - Divisions by zero

I thought: Okay I’ll do 15 of these and start spamming twitter. After I did those… it says I failed for some reason… Am I a bot? I’m starting to doubt if I’m human… 🤔

So what you're saying is that Twitter successfully kept out a bad actor.

It's a shame that most of the users they have left are also in that category, but hey, they seem to be working on it.

Is it immoral to troll a platform that is owned by an evil corporation?
You trolling the platform, or the users?
Users exist to be trolled. That is their purpose.
