I've noticed that there are multiple posts from 2016 that appear to have activity today (2/7) in the RSA Identity Governance & Lifecycle community even though the latest post is from long ago.
For example, at the time of this post, Customizing Approval form with aveksa tag 's most recent post was on Nov 9, 2016. However, in "All Questions", the most recent activity appears to be Feb 7, 2020.
Some of these questions are actually attracting answers, which makes me wonder if there is enough of this false "activity" that it will affect more recent questions.
Edit: Attached screenshots showing the dates that are visible to me.
