Okay! We have headmate selling process now! Let's go over this!
1. Get Consent of the Sold Headmate
Cool start. Consent is important. I do feel ethics can still be shaky with headmates who are made to be sold, but I don't feel it's quite equivalent to slavery as some suggest.
2. Get the information on Carrds/documents
This is interesting. It makes sense to market the headmate. Although the other variation of this I heard sold documents themselves. I assume that particular method was to trick the consumer into reading the material later, introjecting, and thinking it was a successful hop.
With this method though, if all the information is available upfront, you can just browse the headmate market looking for headmates to introject for free!
4. Negotiate price after finding the buyer
Well this is very disappointing. Here I was hoping the prices would be public so I could see what the going rates of headmates are. What's even the point of this if the prices are a mystery?
Seems to be utilizing the sunk cost fallacy a bit here too. Get someone invested before talking over prices so they'll be more likely to spend more than if you had given them the price straight-up due to all the time they already put in.
Good practice. Make sure the headmate is still okay with this.
6. Pay first, get the headmate later.
System hopping is a totally real practice, right?
And this is definitely not a scam?
And the headmate can leave a system any time they want, surely?
Then why not offer the headmate a visit on a trial period to prove that this actually works?
Headmate visits for a few days to a week week, spends time with buyer, and if they're compatible then you can complete the transaction.
Okay, but my advice for avoiding scams is to not buy an invisible, intangible product that's supposed to magically be transported to your head, with no possible way to verify if you received it or not, or seek legal recourse.
