Just as a heads-up: People who complain about "you also make art that I don't like" are often trolls who are not interested in your art in the first place. After all: NG offers a very easy and convenient method for hiding "A"- and/or "M"-rated submissions - with one single click.
Think about it for a moment: If they did 'not' want to to see "A"-rated art, they would hide it with the filters. And if they hide it... - how would they know? Somebody saw a struggling artist (registered since 2023, zero forum posts, "over 28 Art Portal submissions" but only 14 followers) and saw an easy target. :/
If they 'really' had been interested in you as an artist, they would have told you to maker an 'NSFW-account' (like "NogginStudioNSFW") and 'move'* your art there - instead of deleting it.
You can move your art between accounts using a method I describe elsewhere in detail:

(Search for "I want to have an SFW account and a separate NSFW account.")
Don't just take 'my' word for it and do your own research before you take drastic steps. Ask your peers in the Art forum if you want more feedback on the matter:
