If anything it will only add uniques thus valuation thus offers on the table thus better deal

On the other hand, it will cause this thread to come up in a Google search for "<site_name> acquisition", which could have a negative impact on the deal. (Although putting a link in a user profile might not have the same consequences...)

Add a tinyurl (actually use another service that let's you delete links), then delete that link in like a day :)
