To make the comment posts for blog posts more usable, we switched the ingest from the embedding scraper to RSS for the sites that use the forum as comment engine. Sadly that means all the old posts in the RSS feed get updated now or even newly added because we have old posts in the RSS feed that hadn’t been scraped yet. This should be a one time event but in the end we get something more usable. Sorry for the noise.
Sincerely your pixls.us team.
