I find shadow banning disgusting. Makes me angry to have legitimate thoughts silenced through some simple switch just because of some temporary "undesired" behavior caused by my nature of having a plethora of emotions that varies depending on many factors.
I do not like it either but the main use for it in forums I have been involved in was to protect the forum from being destroyed by mentally ill users and the people responding to their incoherent rants. Banning them never worked.
