As fun as it is to call people out and respond with those oh so wonderful and petty responses, this needs to be your go-to from now on. Even if they get hostile, respond like they're not being that way. Of course, stay firm. Politely and respectfully tell them that demanding... requesting?...demanding?...requesting? Free services are just complete bs. Or, if they become hostile, just turn the tables. Tell them while you appreciate their offer youre going to have to counter with them paying full price for the cake and you will be oh so nice and throw in, for free, some posts talking about how awesome and wonderful they are so that they can get more followers from it. It would, of course, greatly benefit them. After all, you've had news stories and stuff done about you, people know who you are. Also, idk what the laws are there but it may be worth putting some kind of disclaimer (small print) on your site that says anything from first contact until the moment they take.possesion of their order is content youre allowed to share and use your own discretion as to whether or not you hide names (no sensitive info like cc numbers or addresses will be shared only public info). By contacting you, they are giving their permission for it to possibly happen/be used. Again, idk the laws where you live, but this is the type of thing that can CYA in the States. Even if you haven't yet run into a real issue of someone taking legal action for sharing something like this, it's better to CYA.
