I do shout outs for when my members make cam sessions fantastic, which is something I copied from workers who were calling out fun sessions they had with clients. I find it makes the members who tipped and joined in the fun for that day feel valued and appreciated, and it's advertising for your next cam show. For example: "Thanks for today (x member) - I had so much fun when we (did x-y-z)." You can even add a screen cap of something silly from the show.
I do this as well on occasion but you have to be careful because theres a few tippers/big tippers that would rather not be called out on twitter. Not sure if its due to tip poachers approaching them, or what but lots of my regs didn't want me to do that. Safer to always ask first.
