I am in agreement with @jacleric when he says put your money where your mouth is and with @inkedodie when he says stealing or sharing.
I’d like to add my 2 cents (pun intended). First, none of the models owe you anything. Don’t expect favours or special treatment because you compliment, tip, like or follow. You should do it as your own thanks to them for what they are doing. If you make other arrangements with the model, then that is up to you.
Second, SG states in their rules that they retain 20%. And that a model needs $50 US to cash out. Which means, mathematically, that roughly $63 US in tips will give them $50.40, allowing them to access their money. There are too many models who need the money in their lives, but their balance is at $40 or something. Not saying you should only tip out at $63, just saying to keep it in mind. Every little bit adds up to that total.
Last, if you can’t tip, always try to leave a like, follow them, and comment. If you can leave a detailed comment, great. Even a little positive praise goes a long way.
If I follow a new model, I often try to go back and leave a like and comment on all of their sets, even if it spans back 15 years. You can go to their profile, drop down photos, then drop down to sets to see them all, quickly.
I love that this was brought up and we are discussing it. Thanks guys!
