Welcome to Steemit. Some advices for starters:

-Reduce the number of posts and increase their quality. Creating too many articles is considered spam, however there is not a strict number of how many posts you should post. Furthermore, posting too much you will burn out your resource credits and won´t be able to post for a certain time. If you consider you need to post or comment more frequently you can buy Steem and power up to increase your resource credits. Check your resource credits at https://steemd.com/@nydsius

-In Steemit the most valued content is the original content. If you decide to start doing original content, you may be interested at veifying your identity in one of the original content services availables, for example https://discord.gg/sP7YHdU

-The nsfw tag is mandatory for nude content.
