Unfortunately my image of this little planetary nebula was one of the casualties of the recent data loss, so here it is again.
This is NGC 2242, to be found in the constellation of Auriga, 6500 light years away and 1600 light years above the galactic plane. Until 1987 it was classified as a galaxy but its infrared emissions and lack of redshift got it reclassified as a planetary nebula.

If this user has been harassing you, and you shadow-ban them, all their activities on your content will be invisible to everyone except themselves.
They will not know that they have been shadow-banned, and the goal is that eventually they will get bored while having caused no harm, since nobody saw what they posted.
You will remove your shadow-ban on this user, and their comments, messages, etc, will appear again on your content.
Such limitation improves the website as a whole by discouraging people from creating fake accounts to like their own content. Thank you for understanding!
