In my experience these type of comments come from the light-blue user group. These users are those who have previously purchased tokens, received them as a model, or have recently tipped less than 50 tokens. You can block them with this bot :
https://chaturbate.com/apps/app_details/lock-light-blues/?version=&slot=1, which isn't free but can be made available to your CB username for a relatively small amount of tokens.
For some free chat control, you can try this bot :
https://chaturbate.com/apps/app_details/the-anti-spam-bot/?version=&slot=1. This bot filters chat, which allows all users to talk. You can specifically choose to filter grey chat or both. If a user types a blocked word or phrase, their chat simply does not appear to the public. The bot contains an extensive internal list that blocks about 95% of current spam trends. You can add specific things to the bot to help filter your non-grey users. You can also link specific things together to block more complex phrases from chat. This bot has a few simple commands that allow you to update your block-list when ever you need to.
To block grey chat and/or allow it but automatically filter most spam, try this bot :
https://chaturbate.com/apps/app_details/silence-grey-chat/?version=&slot=1
These bots will work as well as a Mod for blocking spam or specific things from appearing in chat. However, they can not make judgement calls. However, they also can't direct, yell, flirt, act rude, or embarrass anyone.
There are many other bots that exist for hiding things from your chat room. But I didn't write those so I don't know what your experience would be.
Cheers,
