Alex refused to fix it as it wasn't an issue with Soapbox (as it was working as intended), but was instead a case of someone purposefully breaking their own instance.

Improperly handling compatibility CSS classes was/is a Soapbox bug. What essentially happened is that Pete wrote an MRF that wrapped all posts in <span class=something>#{message}</span> and forgot about it until he restarted the instance.
