It is totally allowed to discuss other travel agencies and businesses. The only rule is that you have to use the full url of the agency or business.

If the agency/business is banned from the DIS, the DIS filtering software will xxx out the url. The only time threads get shut down is when people try to get around the filter by using acronyms, descriptions, etc.
