Yes, everything about the old two-way ignore feature was understandable, except how entire threads became inaccessible just because you ignored/were ignored by the user making post #1. To me, that always came across as more of a database programming error than something logical and useful.
Please don't re-implement a solution that singles out the first post to be more special than the second, or 99th.
(Not seeing the individual post, however, is fair)
Thx
