You do not need to put #peakmonsters as a topic-tag for this post. There is no real benefit and the post is not about PeakMonsters.com so there really isn't a reason to. Those that view the #peakmonsters topic page on Hive will likely want to see posts about PeakMonsters.com. We suggest you use that space for another topic tag that will help your post more and is more related to the topic of your post.
We love seeing posts about PeakMonsters.com and if you create some please include that topic-tag. We often vote and even tip some of the best content.
I hope this has been a helpful educative comment.
