Who's done this? I have
Where can I find these sellers? I have a long list of them I can share them with you directly with you upon request.
What are general tips/trick when buying these? I wouldn't spend more than $25-$50 depending on the reach and engagement the page has. websta.me is a good tool to use when making sure you are not getting tricked by the seller.
I can imagine you need to make sure they have engagement, they can like immediately after you post. but what else? websta.me and common sense. Followers can be faked and likes can be faked, but comments can not. Well its very hard to fakes comments so if you see a lot of comments that is a good sign the page has great engagement.
