oh i completely agree with where you are going the question i guess is does lying and failure to keep a promise to s fellow forum member count as breaking a rule?
havent really thought that much about the enforcement side of things yet... thats why i said i may have questions later... lol
keep the thoughts and issues coming i would love to hear more
You could start with a lend limit, example 50 akorns, if they user pays, you could consider him of trust level 1, after that, he can get 100, then 200, etc, and his trust level will then increase until a certain amount (when it reaches 1000 akorns, as an example), so he becomes fully trustworthy, and free of the limit.
And, if the user for some reason refuses to pay, you just add him a untrustworthy list, and makes him unable to get more money in the future, we can't really take his car or house, so its better to accept the loss.
You could also add some pre requisites, to use any of the services, example, you need an account with at least 1 month old, 50 posts (maybe also 10 reactions), to not just give money randomly.
