A stain on my screen

I was replying on a forum and, after replying, this is what happened immediately afterwards. Where could this have come from? Has anyone had the same experience?

this is most likely a troll text from one of the commentors or something, do not worry, just report the note responsible for this

and how do i report ? and i don't know who is responsible. i just join the club

Message me the forum. I'll report it.

Yep me too

How do I do that? Are you referring to a direct message via the forum? Sorry, but the translation I have in French is unclear.

Someone posted that in the topic. Depending on where it is, will determine who can do anything. But it's not a bug. It's a side effect of allowing HTML support on pasted content.

And what can i do ?

that looks like a glitch in your computer like something is physically broken not a bug in chess.com

Where is that posted?

no no no guys its zalgo text anyone can post it see?
