I'm for anything that makes this site more secure.
The very reason I don't mind the overall needed change in the first place.
If typing a few numbers or letters ... or identifying a few objects to prove I'm not a scammer is all it takes, IMO, it's worth the effort.
I despise Captcha....apparently I'm only half human as I seem to fail on the first attempt about 50% of the time. However, I would never run a site that accepts uploads without that protection. Many years ago, the FBI knocked on a buddy's door because his site was loaded with child porn. Fortunately they were able to clear him before the investigation went too far, but just the accusation of such charges could be devastating.
I run CCleaner habitually (dozens of times a day) on all my devices. Internet cache/cookies are a breeding ground for viruses and security exploits, and I'm going to keep my clean....even if it takes me a couple attempts to identify all the pics with airplanes.
