...Anything but MLM, ponzi, and HYIP, for me, I don't trust them, but using the names of a legit business to scam, well, that is bad, we should look into details which is real and which is fake.
If someone is illegally using the project's trademark, then this is enough to call this project a scam. Using the name of another project is done intentionally to mislead the user. Thus, the participant has confidence in such a project and may lose their money.
Agree with that and they can make it look similar so it's really necessary for the potential investors to make further research.
Some scams which is not related to the topic are those scammers imitating the site, one example I saw was a mixer site, the chipmixer for instance, there are some fake sites where if you send money, your money will be gone forever as there's no way you can go after a fake site.
I guess OP was just sharing, he wasn't scam yet so there's no scam accusation, maybe the right board would be reputation (
