Crypto currency pump and dump schemes for the most part.

I would strongly advice anyone interested by the labels frequencies of dataset to get a look at the json file provided. Interesting thing is not that much the frequency of X or Y labels, but the frequency of one set of labels. (this would be a great addition on the webpage actually).

Pictures can have multiple labels. And so, having the ratio of "Forum + Drugs + Finance" vs "Market-place + Weapons" dispense more information than just the global frequency of "Finance"-related pages :)

Very true. Most of the finance or market-place websites are scam. Not all of them are labeled with it (because there is a SCAM label ! Can't truly test all websites by ordering the stuff) but clearly some of them were scam. In particular techno-stuff (IPhone etc.) marketplaces are usually scams.

Usually? Always. There are a plenty of legitimate services that'll fence such items for you, but they'll just sell them very near retail on amazon/ebay/whatever.
