I have learnt this the hard way! Being a new user I was excited about what Steemit had to offer. I thought that to raise awareness of my blog I could let people know about it in the comments. This combined with liking my own posts (which is also apparently a no-no!) destroyed my reputation to the point where I cannot even post anymore :( I think I will now have to quit and start over again or leave the platform for good. I wish I had of found out more about the rules before I started commenting lol
