Hi, when cheetah upvote you it usually means that you copied and paste stuff. You should mention your sources below your post and also all the images where you got it from. Neglecting to that will lead to other steemians flagging you.
Then if you comment on people's post and it see as spamming by dropping your link there. You won't gain followers like that. Look at peoples post that you are really interested in, read it and make a good comment on the article. Say nothing about your posts. If you keep on doing this you will gain followers that is interested in your work and will upvote you.
Good luck on your steemit journey.
