OP, You have a thing going on here. From what i understand, this is an idea of using a web of trust to verify transactions. Consensus to be arrived at by building and utilizing a web of trust. Its like an online version of a bunch of clerks maintaining the ledger in banks in old times.

I doubt its usage for settling transactions but the idea itself is worth exploring as it has potentially several applications in the times of Social media. I would follow this. I have a small but important request for you to kindly consider.

If its a "web of trust" we are looking at, please keep a condition that people who have used alt-accounts for spamming and have negative trust feedback should not be accepted. The condition for "minimum 8 posts" is pretty weak, especially considering that you have an ages old account at the forum. If this isn't a bought account, you must be aware of the mass manipulation and scamming this forum has gone through. If you are looking to start a web of trust, wouldn't it be prudent to have some sort of best practices??

Good Luck!
