It's a bit naughty that, IMO. The fact that even Salford fans are saying it shouldn't happen backs that up. Their situation is unfortunate, but one that all clubs just have to accept on the rare occasions it happens.
Kind of forces us into a bad light unfairly, too. If we now refuse (as we should) we look like the bad guys trying to take advantage of their plight. If we happen to lose we'll then also be ridiculed.
