Pinterest usually bans account mainly on spam overuse (subjective) and on angry moms that flag you. Seriously. If you think an angry mom sitting at home might be upset that she ended up on a blog page covered in ads rather than a nice, neat mom-ish little page with a large version of her precious cake images that she can pretend (in her mind) to stuff down her filthy, cavernous, gullet (complete with detailed recipe and How To video series on how to make cake in general, in multi-language write up and digital brail no less - since she lost her vision to sugar-slurm poisoning),... if she gets YOUR page... man... watch out... heh. She's gonna flag you. All it takes is one or two. Sometimes just one. This triggers a manual review of your actual endpoint page. If they (the Pinter-elder Gods) so much as THINK it's just an ads site, you're toast. I would know. I run 6 Pinterest accounts + 6 endpoint sites and the key is keeping a SUPER low profile, pinning everything that LOOKS official from your site and for God's sake make sure your endpoint site looks legit and professional like an actual business (can have ads, just make it all look good and REAL). You can totally VERIFY your site with them. Not verifying your site is just another nail in your coffin when a manual review happens - it's a signal to the Pinthulian Old ones that you are scared and have something to hid! ... Then, when flags happen (and they still might), the Pinterest elders will squint thoughtfully at your site, see that her precious picture of bile-cake actually IS there, and simply send blow over it, shambling on through to another dimension, to find easier, stupider, uglier looking (obvious) MFA type sites upon which to exact their gory ghost-ban-dorum vengeance. My experience is all. Cheers. All hail Cthulhu. (dunno why I dropped that last part in there, but whatevz...)
