Sure, but it wouldn't take a lot of tuning to update a bot to read the animated frames and then you're back to square one. In fact, with 20-odd frames and only three (entirely upper-case!) letters to select it looks very easy to develop a bot that would get a very high success rate.

- calinet6 13y agoAre the people using the captcha-breaking algorithms the ones developing them? Probably not. These things take time... the best way to combat them is probably to change what your captcha looks like and works like every week or so.
- leddt 13y agoYou don't actually need to use the motion to improve the success rate. Just run the normal algorithm on each frame and elect a winning solution.
