Since several days have passed and the top moderators involved have responded already, I will follow up here with my own answer to this question...

Yes, WPSE follows different guidelines from other SE communities:

• Most editing decisions are made unilaterally by @fuxia (unlike other SE communities that follow a 2/3 rule which means if 2 out of 3 reviewers agree with the edit, it will be approved)
• Moderator @fuxia will actively "block" users who suggest edits that she doesn't agree with, an apparent abuse of SE moderation tools
• Moderator @fuxia also strongly believes that "minor" edits should not be accepted, as per her previous linking to Jeff Atwood's opinion from 2011:

I completely agree -- reject them, with extreme prejudice. This is why we limit edit suggestions to 6 characters; there are still some hacky ways of getting around that. Sam was against making this stricter, but I am going to overrule him on this and implement more strict checking myself; I would rather be too strict and reject some edits than have to deal with a continal stream of character-twiddling edit suggesting users.

However, Jeff seemed to be referring to edits that are less than 6 characters of modification, such as simply capitalizing a single letter of a word, etc. This is different from @fuxia opinions on this page, e.g. that even extensive improvements to question titles (etc) do not improve comprehension, and should be rejected immediately without proceeding to the 2/3 reviewers rule...

Such opinions contradict the more popular opinion, quoted below:

Edits should be accepted if they are correct or helpful, and rejected if they are incorrect or spam. The length of the edit is irrelevant. Who cares if the edit is tiny or major as long as it's improving the quality of the site's content? The reviewer's time has already been used in checking the edit, so nothing is lost in accepting it. The How to Edit box next to the edit window encourages exactly these kinds of changes, so it would be pretty hypocritical and counterproductive to reject them...

In affect this SE community is actively discouraging contributions from new users, and is also preventing reputation from being gained by new users, since @fuxia controls nearly all moderation activity, and because she continues to reject most suggestions being made by other users, while accumulating thousands of reputation "points" on SE with her own moderation activity.

Accordingly, I would suggest WPSE reconsider how this situation risks turning the community into yet another online "fiefdom" of over-moderation instead of a collaborative forum. I'm no fan of "government by committee" but when 1 person is rejecting the majority of edit suggestions on a daily basis, and then "blocking" users (like me) who make suggestions that she doesn't agree with, it certainly appears to be harming the purpose and spirit of the Stack Exchange platform (esp. noting the popularity of the WordPress SE community).

Cheers, and thanks for listening --
