VRChat mods only check avatars if they get reported. Not getting reported in the first place would be the easiest way to avoid trouble.
The easiest way to not get reported is to stick to doing lewd things in private instances. But even in public /vrg/ instances ("friends+", that is), most people won't mind lewd loli avatars. You'll easily know who will mind and avoid confrontation about that, if either of you is willing, though.
In public-public instances (non-/vrg/, that is), people are far more likely to mind, since that's where you run into normalfags who just join for a few days. And that's where people usually get reported for lewd things.

The intention of the rule against avatarfagging is to prevent anonymous posting to be easily identifyable by anyone and to prevent annoying clutter detracting from the post, like signatures do in a normal BBS forum. That's why >>>/global/rules/13 is about BOTH "avatars" and "signatures". Historically, it referred to people consistently posting the same character in their reaction images or non-reaction images attached to literally every single post they made.

To call posting a screenshot of a friend's avatar, which isn't even your own and changes up all the time, mind you, is a false equivocation of the term "avatar". In addition to that, since every depiction of a user in the game VRChat by definition has to show someone's avatar, you wouldn't be able to post screenshots of any person's avatar in that game, which would greatly hinder discussion of the game and be absurd.

Therefore, posting screenshots of friends' avatars is allowed, and even posting your own is allowed, when done in moderation.

(If you still disagree with that, you are free to make a report and await a mod decision anyways, but seeing as almost no avatar screenshots get deleted, the mods approve of posting of avatar screenshots most of the time, despite some people reporting furiously.)
