Considering that these threads being reshared are usually a few threads down the latest feed, it makes sense to re-thread with a personal thought.

Re-threading solely for more visibility isn't quite reasonable.

Good point, definitely ads a spam feel when there's many of those re-threads above each other

They are rethreading to get a Boom upvotes, and it's like a spam when they don't add any personal input on the rethread.

Yeah, so many of those re-treaads, feels spammy alright
