Will a collection agency even accept a BTC debt for collections? A collection agency will not bring a lawsuit for any amount under $5,000 US anyway so I don't understand how funds will be collected.
Will the owners of BTCJam call the police and tell them that someone stole your bitcoins? What will the police do about it?
About calling the police, etc, the collector agencies can and will pursue lower values when we have volume. Also, people will pay the lower values as their credit report will be hurt.
About the defaults:
I would also like to note that the service today is far from perfect, but we believe it represents a major improvement on the rater manual procedures used on this forum, good payers are building good reputation profiles already.
One good thing that is already happening is the scammers are being casted out too, we had two cases of scammers trying to get other accounts verified with no luck.
Takes time to build an ecosystem, but it is being built.
We have several good payers and the majority of loans are being paid on time, that being said we think perhaps we should add more moderation on users and listings instead of just let the "system" regulate itself.
