I mean, if in the context those posts were low-effort and didn't contribute to the thread in any meaningful way, I could understand. Like sharing nothing but a reaction gif in a discussion heavy community could be seen as "low effort".
But common acronyms? Yeah, that's definitely a strange thing.
Also, isn't GIF itself an acronym? something-or-other Image Format?
As much as I hate it, there's currently still available a thread on Reddit that provides links to various archives of January 6th info/video/etc. I personally have the 1~ TB video archive data saved and mirrored on a couple of cold storage drives and I'd encourage anyone with the extra HDD space to grab as much as you can while it's there.
