Most if not all respectable artists here either submit their own work or work on behalf of their group. They don't submit it on behalf of a colleague, friend or as a favour, unless they are a go between for a banned member. Many thieves use that excuse, so you can see why @jaguarbeastproduction is so angry. Posting other people's work on here, claiming it to be your own, and being outed for it immediately gives you zero or little credibility. Posting crypto babble also doesn't help your case.
The model has been deleted, but the crying kaws model was from a Russian website. It is doubtful that an artist charging for a model would give it to a colleague to post somewhere else for free.
Most artists here also have a central theme in their work, but the models you uploaded are are over the place, again, damaging your credibility.
You seem like a reasonable person, so take the comments here as a suggestion and try to rebuild your reputation.
