Because the OTCBB regulations do not require a MM to disclose the exact amount of shares being offered for purchase or sale. The OTCBB is not for most real companies to be listed on because their rules and regulations are very lax and prone to possible abusive behavior. That is why it is not the preferred exchange for public companies, but it also has some benefits over the other major exchanges - cheaper listing costs, easier listing rules and requirements......
If you don't like the way this exchange works, make sure to not go to any company listed on the pink sheets!!! Now there's a place where serious games get played regularly.
Perhaps a few minutes spent looking into the OTCBB rules and regulations could help clear some of your questions and give you some insights.
