In the past when you needed less shares, I could see how this could be abused for the privilege of being in the Club for a period. However, I think given the amount of shares you now need (as a new member), I'd think it unlikely anyone would now do what is mentioned above. It's just not financially viable as the small perks and how often you can use them really do not add up to the finance of the new required shareholding. A good thing I think as it shouldn't be abused. Abuse only leads to perks being withdrawn ime.
I am pleased they have increased the renewal period to 5 years though - makes much more sense from an admin point of view.
