Lol.
According to section 7.2, subsection b), point iii), the supporter should advise the club in writing of the contact details and address of the loanee. Also the person using the card mustn't be banned from entering the stadium, etc..
As long as the loanee behaves and complies with the rules, I'm not sure how the club could implement this clause.
If the club turn a blind eye to season ticket sharing, OK.
in truth it's something the club can't regulate on a matchday, so I suppose they have no choice but to turn a blind eye to it.
