Share lending

What is Freetrades current thinking on lending customer shares to shorts etc? Adam suggested that this may be done in future in the discussion on crowdcube R4.

I remember reading on an International Brokers web page that they allowed customers to opt in to share lending and split the payments received with the customer whose shares were being lent. I feel this approach puts customers in control by allowing those with ethical objections to not partake whilst allowing opt ins to collect a second dividend. It potentially also protects brokers from having lent shares sold by a customer.

What are others thoughts on this topic?
