my friend, about the subscribers, I want to tell you that you should have at least 300 of them just for the media campaign. Each of them has its own requirements, for example, on Twitter you should have at least 500 subscribers. I do not remember exactly, check with the requirements.
in general, on Twitter and in general the requirements are somewhat different: there are restrictions on the number of characters - at least 70. Also, merging with several accounts is not allowed, this is fraught with a black list.
