I don't know how to call it but most of you will know.. If I add the someone else ID like @ID @ID at the reply of article, it call the ID owner.. So I think If I use this as a marketing tools, then It can work.. Is there any one who used this already? If I made new account and do that, for more than 100 or 200 people adding,, then what happen? IG just pend my account? How long it will last?
