[pixiv] support answered me, in short nothing, they just copied a message and didn't answer any of my questions, so I still have all my doubts.
As everyone or most of you must have seen, I used to use this format, I put it at the end of each post on [p]ixiv, but I had to delete them all, in the end they never told me if I broke the rules or not, but for safety I deleted it and I will not use this method again in the future.
I thought of an alternative, of the same model, but a little more elaborate, but I think it can still be perceived as advertising.

Well, seeing other normal artists and AI artists, I came to the conclusion of just leaving a watermark and not putting anything in the description, everyone should know that in the [p]ixiv description I like to leave basically an index of all the posts of the month, in theory that is allowed, really given that the rules and criteria of [p]ixiv are not clear, I have to find the method that does not break the rules.

As you can see, the watermark is on the shoulder, or in a corner. This will be the new method. I don't like using a watermark for aesthetic reasons, but well, I think it would be more of a signature and it doesn't count as advertising and [p]ixiv shouldn't have any problems.

I'll try to upload more posts on my secondary account to gain followers in case [p]ixiv just bans me out of nowhere, since their rules are not clear at all.
and on the main account upload the content again to promote patreon, although you know, now with a watermark and for now without a description, I don't like the method, I think it's not very effective, but without knowing the rules of pixiv, that's what I thought.
Follow me on my secondary account in case you already know, they ban the main one.
Thank you all very much for the support this month, the numbers were affected by the suspension of pixiv, but it wasn't as bad as I thought.
The special post of black-haired boys is coming.
I thought of special posts later for boys with blond, brown, white and other hair (orange or green, less common colors)
Check and kaito kuroba has dark brown hair, he doesn't have black hair.
