See the sticky post about moderation - Reddit aggressively removes content from suspicious accounts and that could be why.

Strange though because the thread was open for months and I checked it 2 weeks ago. Weird that they would just remove it when there were so many comments

Things can be retroactively flagged if an account becomes suspicious. The bad actors I've found nurture accounts for months or years before using them to create fake content.
It doesn't mean the discussion was bad in those cases though.

Would you know if there any record of the thread?

I can't find one, do you remember anything about it?
