I was pointing out that when you pay nothing for a web service, and the site in question has no third party ads, then perhaps you should temper your expectations of the services rendered. If you want better service, snazzier websites, etc, don't be surprised if you are asked to pay for it.
Also, I think you may be confusing the main flightradar24 site (that tracks all/most commercial passenger aircraft movements) and myFR24, previously known as flightdiary.net, which is a personal travel history tracker just like flightmemory. At least for the moment FR24 and myFR24 operate separately.
