Abhineet, I think you'll find most hosting companies require an affiliate link similar to the one Blesta provides you. So if there won't be an affiliate link, how else do you expect Blesta to apply commissions correctly? It's a lot more helpful to suggest a different solution than to simply say "I don't like this the way it is right now." The only other way I can see to do this would be to include the affiliate number in the link at first, but then strip it and move that to a cookie instead. That sounds like a lot of work for a fairly minor thing, though.
