Live chat where? On the top games?
Block feature not working in Live Chess Chat - Fix the Spam

Yes, Live chat on the top games. Even when you block spammers, their spam still appears making chat unusable. Some very autistic individuals will spam endlessly. If there was a delay, they would stop.

A dynamic delay, where accounts can post at 5-second intervals until they start abusing it (by literally posting every 5 seconds) and when they do, they get a 30-second delay. This would make chat actually usable in top games.

Also, limiting the amount of emotes per post to 5 would definitely help. Walls of giant emotes make reading chat impossible as well.
Seriously. Introduce a 5-second delay in the live chat. For the love of god. It's a literal cesspool.
People are spamming nonstop making it unusable. To make things worse, the block feature doesn't even work to stop their messages from appearing in the chat. It's almost as if you want your site to be toxic and unusable. Please, lift a finger already.
