Whatever the background to the pump and dump coin you mention it was the alleged hacking that made a lot of victims come forward.
oh about the shitcoin story this damn scammer created:
a few years ago when i entered the crypto world i was making faucet and i realized that making faucet would take centuries for me to have many satoshis so i sold my computer stuff, i remember that day it was raining a lot, even raining i went to the bank and went deposit the money in the bank to buy bitcoin, after buying bitcoin i created an account there on poloniex and yobit, i didn't know at the time that yobit was a scam and so i bought some altcoins on yobit... god in heaven, i regret it to this day. this scammers was on yobit chat encouraging people to buy altcoin from him (I forgot the altcoin name, I think it's called TGV or TPG something like that... ) but after these scammer kept spamming yobit chat, shitcoin was removed and dropped from 400 satoshi to 1 satoshi, only after years I realized that it was this guy who had created shitcoin and was the same one who spammed yobit.
