If someone's acting fraudulently, and they become aware of complaints which may lead to the security being frozen or punitive damages awarded, what incentive does that Issuer have to not take off and give investors absolutely nothing, given that Issuer has no qualms with defrauding investors?
These are the two main issues for disputes: adjudication and enforcement.
For adjudication I think judge.me is a great and cheap alternative and there is plenty of evidence for an arbitrator to sift through like the contract terms, forum threads, etc.
For enforcement I think the issuer should deposit bitcoins into escrow held by GLBSE. The amount of bitcoins in escrow should always be viewable and part of the ticker page just like the contract terms, etc.
Also, the contract page should be 'editable' but all previous versions should always be viewable. Issuers should be able to upload new PDFs that become part of the contract. These PDFs could be monthly or quarterly financial statements, material statements, etc., pretty much like 8K and 10K functionality, and not necessarily changes to the contract.
