Custom Greetings keep repeating. Settings for Custom Greetings

[PurplePoloPlayer]

Hello,

I like to give my regular viewers a custom greeting when they log in to my channel.  A number of them have mentioned that Deepbot greets them multiple times during an evening even though they never leave the channel.  Is there a bug with custom greetings?  Is there a setting where I can limit the number of custom greetings for a certain time period? 

Thanks,

Deepbot has a refresh rate of 10 mins on the user list when updating the user list, so it will automatically say this everytime it updates. There isn't a way to limit it, that I know of.
