Now let’s talk about the tips. You should do shilling so creatively, for example if you want to shill your channel, don’t forward your posts directly and don’t put your channel link directly in the shilling groups.
This action will flag your post and it have some risks for accounts.
It’s better to put your channel link in the biography of shill account and just send some conversation about your business in that groups.
