You should look at a site called cointelegraph, and compare it to cryptozapper.com.

In my opinion there's a clear similarity between the two that simply cannot be missed. It's very likely that they never planned on delivering on your partnership, because they have even shown the willingness to plagiarize others' work, essentially.

It's easy for anyone to launch a news site like this, copy over the template, and all the articles, and look for "partners" to lure in. Nobody has ever heard of this site before, bar the owners themselves, meaning that even if your partnership goes well you'll get no publicity.
