SMM follower sales and tax

[toxicmix]

Hello. I have some connections and advertising opportunities. I am thinking of opening a website and also engaging in the business of social media followers, but understandably, the tax situation is worrying me. There are many people doing this business and almost none issue invoices (apart from corporate companies). Of course, someone not issuing an invoice does not make this situation legal, but it is bothering me. There must be people on the forum who have been selling followers for a long time. Can anyone shed light on issues related to follower count, etc.? I have no idea if this will be profitable. If I move forward, of course, I will do it officially, but in addition to that, what can those who sell on the forum say about this issue?
