Does a jail cell door over an avatar mean?
It means the user has restricted abilities (jailed) due to an issued warning and moderation steps (points) assigned.
Restriction can include:
inability to make discussion posts
can't post as frequently
signature is hidden
You do not want to collect moderation points.
