I agree. I wrote a script that crawled the pages and found about 1500 “projects” that were potential SPAM. I reached out to one of the staff, but I have not heard back.
What I recommended was leaving everything alone on a person’s login but removing the publication. That way it wouldn’t dilute the otherwise good easel projects, and if someone truly meant for their project to be public they could re-publish it.
There are a few submissions that are flat out shilling for investment companies, cosmetic companies and other things that are not in the realm of proper use of the site.
I don’t think that Inventables has done all that they can to curate their site.
