just to clear things up. are you saying that if someone made an attempt to access an account and failed the "last active" will be updated and will show "today"?
from what I know it shouldn’t... beside on what he said above
"Sorry Guest, you are banned from using this forum!
Your account is locked because it sat inactive for years after the password hashes were leaked in 2015, and was therefore at high risk of being hacked. Email reactivate_2019_*****@bitcointalk.org to get it unlocked."
That means he can open it freely though the only issue is he has limited access due for being banned.
If it was just attempting then he shouldn’t be able to see that and just be on the log in page.
As from what I see here he refers to “accessibilty” on the activity which will not restrict him from posting on this forum.
