First off, I was a bit hasty in meriting OP's post. Upon examination, there isn't really a direct connection between the addresses mentioned and the team, at least not that was mentioned in this thread or that I could find. However, what is clear is a pattern of pump n dump product launches. Everything this guy made has gone to zero. I'm tempted to ask: in that case, "why would anyone buy their next thing?". But I already know the answer: its because people know these projects draw liquidity (suckers) and a lot of shitheads traders think they can get in and out before the next guy, knowing full well they are trading scams.

A curious history of company registrations backs OP's claims even if onchain evidence does not. Lets look at the other companies registered under Mark McKenzie:

ONCHAIN INDUSTRIES LIMITED - incorporated Sept 2024, application to strike-off Oct 2024
MEGA BLOCKCHAIN SYSTEMS LIMITED - incorporated Jul 2023, compulsory strike-off Sep 2024
EXITED BLOCKCHAIN INDUSTRIES LTD - incorporated Feb 2023, still active (in debt as of Feb 2024)
APES TOGETHER LTD - incorporated Feb 2022, compulsory strike-off Jan 2024
MONKOSAURS LIMITED - incorporated Sept 2021, compulsory strike-off Dec 2022

So the average lifespan of one of these guy's companies isn't very long and nobody should have confidence in his next venture, or the one after that, or the one after that.

Pump n dumps are the norm for Solana and the INTERN chart looks like 99.99% of all tokens ever deployed on that blockchain. So while this is dirty business, its the norm for Solana. Nobody "invests" in these types of tokens; they are straight up gambling.

If a traditional crypto "start up" token launches on Solana, that should be a big red flag. Its an ecosystem for utter trash and everybody knows this.
