Options are good.

As for displaying vs. not displaying -- I'm speaking only from my own experience here, and YfilteringpracticesMV. But IME, when someone's specific post is being quoted and discussed, it's easy enough to figure out what's going from the surrounding discussion to go back and find it if you want (say by un-plonking the person temporarily, or better yet searching; it should be no harder than going back to find something important you missed when you've skipped and skimmed). But if you'd really rather ignore it, it can be almost-but-not-quite as infuriating to go through page after page of "Joss posted" "Joss posted" "Joss posted"....

Which, thinking as I type, makes me think that I'd like to have an invisible ENUF/MARCIE/killfile/whatever, but with an option in the search feature to include killed posts in the search. And yes, I know that's asking a lot, but I'm in musing mode rather than practical mode tonight.

The missing post could "appear" with something as subtle as a tiny gif or single letter, say if you came across

[...]

in a thread, you'd know it was a missing, MARCIE'd-out post, but there'd be no more than that.

I think we should have the option. If I lose my cool and end up with 17 ENUFed posters (we need a practical cap), then I'll want to know which one I'm ignoring when. So maybe it's post ignored by thatperson postdatetime or nothing at all.

Okay, that's [edit: just having an ellipsis or the like] not that bad -- what I've seen discussed up until now was something more like a full set of post headers (not the right term, but, you know what I mean):

Joss, datestamp, post number, Mark, tagline
this post has been filtered

Which is way more than I want, when I've gone to the effort of filtering someone out rather than just skimming past them.

And, of course, apologies to Joss, whom I would (probably) never actually plonk.

Why not three options: Nothing at all, headers but no content, or my 'subtle' missing-post indicator, forming a link to read it if desired?

As I said, options good. But since I'm not the one doing the coding, I don't want to get demanding about "this is my personal preference so give it to me now!" either.

In all honesty, in all the time I've spent on Usenet, I never missed seeing any indication that some jerk whose posts I didn't want to see had posted!

Gah.

I just realized, that as admins, we shouldn't ENUF anyone.

However, back in the day, I appreciated knowing when I was skipping, and when I wasn't, at least so that I could work out what I had missed on purpose, and what I'd let slip by me.

Why not three options: Nothing at all, headers but no content, or my 'subtle' missing-post indicator, forming a link to read it if desired?

I'd vote for a stripped-down header, that is, something in between. Unless it's actually easier to code for leaving the header much as is. I would like to have the name of the filtered poster appear; on TT I had more than one person filtered, and the reasons differed somewhat from person to person.

But I think name of poster and missing-post indicator (by all means subtle) would be fine. Again, depending on ease of coding.

(Finally, even with the recent shenanigans on Firefly, I don't yet feel the need to filter anyone. By all means take this into account when according weight, or lack thereof, to my personal preferences.)
