I see. You have asked a few that has been on this platform for quite awhile. Not long enough to try the app themself though.
The app allows us to use up to 20 tags. Why shouldn't we use them? How is this even a problem? Does it insult someone that she posted 10 tags? Did it make someone's day miserable?
People start flagging because they are morons, not because of tags. It's as simple as that. "Oh look, she posted 10 tags! Lets buy some more steem to make her go away!".
Guess what. Other people use more than 5 tags too. Go teach them! Send them more threats! You have the power! MOAR POWER! MOAR!!
