You've hit on a real conundrum here. FullRBF's power is clear, but it's like giving a supercar to a teenager – it can be used responsibly or lead to chaos.
How can Full RBF lead to chaos? 0-conf transactions can be double-spent, and that is true since 2009. This particular node policy will only standardize it. Nodes could have configured that out long before Full RBF, and I'm pretty sure some mining pools did pre-configure likewise.
Let me change it, I used to use imgur and always used lower size images, but sadly that hosting is not longer working on bitcointalk.
Consider using
talkimg for uploading images on bitcointalk, as it's specifically created for that purpose.
