I am doing it to other users as well, when I am browsing the tag, so it wasnt just to you. Other users with higher level are also doing it either manually or using bots such as cheetah and steemcleaners.
There are 1 million accounts on Steemit, it is not an easy job to go through one by one only by a handful users.
Sadly it is an ongoing problem we have on Steemit. Since you already could see there are tons of abusers, please don't be part of the problems.
I have crappy phone that I keep editing this comment, so much typos 🤦♀️
