I'm not sure everyone who could play against VS are 24/7 on TL and waiting for their opponents to buy players, so they can write down the skills.
you don't have to watch the tl 24 hours, there are only few players out there, who are intresting for an instant boost in this competion.
The thing if it is unfair, or a discussion about teamstrategies of b3 participants could be done but as long the players ain't on the TL atleast they don't broke a official rule.
