As you already found out many on the platform get upset when newcomers focus on just the earnings. Some have very poor social skills even on social media. I think some are bored and going around finding posts they can complain about.

Earning money takes time. You need to read a lot of posts and comment on those you like. Upvote them even if you do not have a lot of power. It takes up to 7 days from comment to getting a small payment. In time it all builds.

I borrowed the following from @SCILWA:

First it takes time to build steem power (SP) . Some of us bought steem to get started when it was $0.20 or less. Many start earning by visiting other's posts and upvoting (even if little SP), but more importantly by commenting. Good comments can generate SP. Have to wait 7 days before it shows up in your wallet so be patient. Some do a lot of re-steeming, but that works best from my experience when you build a following.

Read through some of the introduction posts to see how others did an introduction of who you are. you can go to: https://steemit.com/trending/introduceyourself

I spent some time on Steemit before I did an introduction. Some do one early on and then do another when they are more familiar with the format.

I recently read an article that would be perfect for you to review for newcomers. Check out:

Hope this helps. Ween you do an introduction post let me know and I will resteem for you.
