Have seen this called both Blue and White Snowball. The color is from the RGB, so IMHO it is blue. O-III was used for L. The drizzled version (here) was much better than the un-drizzled version.
It is very small: 1.1 Arc' in diameter on the long axis.
This nebula exhibits some evidence of an interaction with the interstellar medium, along with a characteristic central torus and outer halo. It may be similar to NGC 2371, but older and with a less constrained wind.

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!
