First of all, welcome! Secondly, in theory if people that post content your not interested in join Hubski, it should have little impact on your experience. -If you don't follow them, you will not see their posts. If they post to tags that you follow, then you can "ignore" them and not see their posts. If you find that they comment on posts that you comment on, you can mute them and you will not see their comments.
We have built in many controls for you to be able to tailor your experience here. You can follow/ignore tags/users and domains.
CameOutOfTheTrees, glad to have you here, if either of you have any questions feel free to shout-out or pm me.
Enjoy the site! See you around.
edit: I should mention that we are always open to suggestions as to how we can protect the integrity of your experience here. Our goal is to be a trusted place to find, create, share and discuss the most interesting content on the web. -Any ideas to help support this goal is most welcome!
