What do you expect? The whole purpose of pump and dump is to scam people. Almost everything in the crypto world is a scam. Faucets that don't pay, wallet maintanence mode to steal your deposits, fake coins and icos. The internet is full of liers and cheaters. There is very little that is genuine about alt coins. It's the wild west.
Just check out this huge list of scam sites:
http://www.badbitcoin.org/thebadlist/index.htmThis doesn't make the general crypto world a scam.
People that want to scam are obviously looking for anonymous ways and cryptocurrencies are like a heaven for them. Same thing applies for drug dealers and criminals. However, this doesn't make cryptocurrencies a criminal's currency. We're using it and we're not criminals. Do you really think it's used by them in a bigger percentage than us? I don't think so.
Scam websites will always exist. No matter if it's crypto, tor or anything else, they're gonna exist. Find a list of scam websites that aren't linked to cryptos (like Visa, PayPal etc) and you'll be surprised....
Pumps are made for people to quickly buy so the price goes up very fast, and then the whales are selling and making thousands in profit.. they will also continue to exist. This is why I love Bitcoin the most.
