no. and it's dangerous to equate them.
there's reasons why both may be undesirable in specific settings, and instance admins will need to make their own decisions on that, but the reasons for that are completely different.
mobile.co is an alt-right politics-oriented instance.
honey.church is an LGBT instance which do not accept certain segments of the queer community (the people who want to replace LGBTQIA+ acronym with MOGAI, notably).
by equating the two together, you lead people to make bad moderation decisions. instance admins need accurate data in order to make good moderation decisions.
to say that you should block two instances for being the same, which in reality, have completely different rationales for why one may want to block them is intellectually dishonest and a disservice to the fediverse admin community.
finally, admins should always look at activity on instances and draw your own conclusions, instead of just going on suggestions, this post is an example of why that is -- the information is defective.
mastodon instances have a third-party timeline viewer (http://www.unmung.com/mastoview) which works in most cases and pleroma instances can be viewed publicly without any special tools in most cases.
