There's always new people in every forum. Who often impulsively reply only to the original post or to the most recent post... even if it's ancient... without bothering to read anything past (maybe) the first page of the topic... dredging elderly "necro" threads back into active forefront.
PM Community is also typically (and half-mistakenly) perceived as an official tech support forum. So many people come here specifically to request/demand their issue gets fixed. And they will basically click on the first thread they see which had a "solution", a PM Moderator, or an Oracle in it because they assume that'll get fastest response.
Some forums get very snippy about such stuff. PM Community doesn't seem to get very upset until "bad netiquette" incidents begin to consistently drown relevant topics under an endless deluge of dead topics. I don't think I've even seen such problems persist long at this forum - there have been surges of deliberately offensive posts (from disgruntled customers and from random internet trolls) but evidently things were somewhere resolved behind the scenes.
It's public internet so you'll find critics, pedants, and cynics ready to complain no matter what you do. So I'd advise not to worry too much about it. People will let you know if it bothers them. As politely as they're able.
But it's refreshing to see that social consciousness still exists online. 🙂
