Evidence
This spam is not through Whispers. This is through normal chat. They also seem to be spamming some kind of code between each spam message.
Seconding this issue. The spam of some bots are breaking through the block list.
edit: not entirely sure, but these bots might be using letters typed in ascii or some other alternate keyboard code. they’re not showing up on my block lists when you right-click block their chats
Isn’t the “Team Name” slot in these reports for the botters/rule-breakers you’re reporting? If so, ya just reported yourself. 
Also, “Blocking” only seems to work for Whispers and Shout, at least from my experience… I’d prefer it if it hid the user completely from any sort of interaction. 
As for that “code,” it is probably just nothing more than a preventative measure the bot is taking to bypass any possible measures the GMs of a game could take (such as setting it up to disallow repetitive postings of the same message back-to-back).
Thank you for bringing this to us. We will now investigate the report.
