kojira, I don't know what the circumstances were with the companies you were referring to, but the OTCBB listing requirements are quite straightforward:

http://www.otcbb.com/issuerinformation/issuerinfo.stm

"The OTCBB is not an issuer listing service, market or exchange. Although the OTCBB does not have any listing requirements per se, to be eligible for quotation on the OTCBB, issuers must remain current in their filings with the SEC or applicable regulatory authority. Market Makers will not be permitted to begin quotation of a security whose issuer does not meet this filing requirement. Securities already quoted on the OTCBB that become delinquent in their required filings will be removed following a 30 or 60 day grace period if they do not make their required filing during that time. … Additional information regarding that process can be found in our FAQs. To provide evidence of compliance with the filing requirement, contact the OTCBB Issuer Filings Department. For more information regarding the eligibility requirements for the OTCBB, refer to Rule 6530. "

So basically that's all there is to it.

There is one other point: they have to have a market maker. But as far as I understand, that's just a matter of money.
