Doubtful. Updates happen on thursdays. Also jagex would never end f2p. They spent so much time trying to kill off the f2p farms for them to end it.
Also in terms of catching bots, f2p bots are the hardest to catch if you're doing it without jagex handing you the data. They barely show up on the highscores. For p2p bots, you can find bots easier, but still hard to differentiate between bot and a fucking vene.
