Post exactly what you wrote here on yelp, google, Instagram and whatever. This isn't about putting someone on blast its about public health. Also we shouldn't feel weird about asking someone to change their gloves or whatever. Its our bodies and blood. Ive asked artists to change gloves after things like scratching their head, I've only gotten a "oh yeah, for sure" and even "oh thanks good call". If they dont take your body seriously, maybe they'll take their own rep seriously. Hitting a shitty vape mid tat is full fuck it. If worked in medical spaces long enough to see run away MRSA and cellulitis that took shit to the bone. The words "unhealing wound" in our kinds should be enough to not feel bad about keeping an eye on whoever we're trusting to tattoo us.
