Hello @snowpea
Tagging is not wrong in my opinion if it used within the persons post. And when it comes to sharing links in the comments section there are exceptions.
There are times it can be done at the request of the Author of the post or you can link someone who asked for that information in the comment section. And like this post there are some posts that I try to get across to people because I know that it will be valuable to them, but I always ask their permission first.
I suppose maybe that's something I need to scale back on a bit. Thanks for the advice! :)
