my two cents
Q posts aren't the same as Q-like posts
Saying a post is Q-like is saying it bears a similarity to posts made by Q
not the same as saying it was definitely made by Q
Making it notable enables people to look and judge for themselves
Just like putting a question mark at the end of a notable when it's interesting but hard to verify is ok. Bakers often do it to point to things that may be worth a dig.
Ditto for an anon's well-reasoned thoughts or theories that may be of interest to Q patriots. These often get skipped over because they are hard to judge and don't come from an official source (like the msm). But some are a lot better than what the msm dishes out.
