I got timeout for asking someone whether he is using the keyboard plugin or not!?

Hey there, I recently played an hourly ultrabullet arena and I asked a player in public chat whether he is using keyboard or not. He wrote "Yes, I am using kb.". Few days later I played again ultrabullet arena and this player was there as well. Somebody asked in chat whether this person xyz is using keyboard or not. I wrote "Yes, xyz is using keyboard. :/"

Few minutes later my message got banned for PUBLIC SHAMING and I got timedout for 10 minutes.

So two problems:
I Why do I get timeout for writing that someone is using keyboard plugin?
II Why does writing that someone is using keyboard plugin count as public shaming? Public shaming involves that this is something really bad (e.g. when you write "xyz is cheating" or "xyz is playing bad").

So, from this should follow that lichess thinks that keyboard plugin is bad and unfair. Otherwise they wouldn't have timedout me for writing this with the argumentation that it's public shaming.

Am I wrong? Or is this some kind of lichess bug? I wasn't sure. If it isn't a bug pls remove post here.

Can I ask why you even asked that question in the first place? What difference does it make to you whether a remote individual is using a keyboard, iPad, phone etc as long as he is not cheating. Why did you feel the need to ask?
