in my opinion, AVATAR can be defined (used) in a very diverse way...
-as a tool for psychological influence
Let me explain with an example from online poker - being a true pro, and believing that there are no small details, a regular player, based on the geographical, racial, age (and other) characteristics of the table, can change their AVATAR (... An AVATAR depicting a 3-4 year old crying baby, pathetically covering their face with their hands, will be more effective against a table with a predominantly female and/or parental composition; a semi-erotic AVATAR, ready to embrace two brutal KKs, will be more effective in another table) - again, depending on what emotions the AVATAR is intended to evoke on average - is it considered beneficial to anger this table, to evoke pity, to amuse, etc...?
From this point of view, a certain anomalous surge of female AVATARS (hmm...av-gav, a pun, by the way...) can be seen as a well-thought-out and skillful influence on our sexual instincts, "nothing personal, it's just war"...
Of course, there remain more prosaic motives for this anomalous AVATAR surge (with varying degrees of probability):
-an elegant virtual retreat and a skillful posing in the Childe Harold pose, like a "NotLikeEveryoneElse" attitude
-a herd mentality,
-e-e, let's say...latent sexual deviance,
-pornographic motives, similar to frivolous cards in a harsh male collective (army, prison, monastery),
-finally - not without some pathos:
reflection of the inner world as an artistic perception
