What are those symbols/sigils?

[Account]

I only know one sigil/symbol on that image unfortunately. What does the others mean? Or are they not known yet?

Please only respond if you have serious knowledge and know actually what you talk about. I am looking for serious replies. No trashtalk or blasphemy.

Zooming in on your profile picture you have 2 circles around a sigil, make them disappear they are an insult and a ligature.
