One thing I have noticed about Medium writers is how observant they are. I am the world's worst observer. If this exact situation happened to me (which I am positive it has), I would be like, "They liked two of my really old stories and immediately followed me. 😍" I wouldn't think to look into it or question it haha.
On a serious note, it is so annoying how these people work. Because I am 100% gullible enough to give my support and time back to them when I could be supporting actual supporters. It's such a cheap way to get people to follow and read your stuff. 😒
