LLLLL domains are just too speculative. They either need to be an actual word or a brandable name that is catchy or pronounceable/memorable. IBSAG just doesn't have either of those and is also a possible trademark issues with the company IB SAG out of Switzerland. Some domainers are buying these up as all llll .coms are gone. I am note sure these will ever follow suit, at least not for many years I suspect.
