@thisismissem well I wouldn't phrase it that way as "recommended" brings in the subjective.
it would be fair to warn people that, "This instance is included in blocklists so be aware that its reach is to some extent limited" or "be aware that its feeds may not reach as much of the fediverse"
Sure, inform people, but a recommendation for someone who cares about such reach will be different from someone who doesn't.
Some people may even prefer a less-integrated experience.
