As to how to complain in this thread (or other troll call out threads) about some post or poster without cluing them in, but with making it easy for your audience here to see the post(s) you’re talking about …
Quoting myself from upthread for context …
I tried a new technique today to point out a problematic post and poster. It seems to work great; even better than my technique quoted just above. Easy for the reader if a wee bit of work for the complainer. To wit:
Create an advanced search that returns just the post you want to highlight. Then include the url of the search in your complaining post in the complaints thread. Anyone who wants to see the problem post clicks your link, which produces for them a fresh search page with one result. Which result they then click to be taken to the offending post.
See here for my first such post as an example. And note there’s no backlink to there anywhere in the problem thread.
