The Nine-Second Hand Check
Before your first post, you hold your phone in your dominant hand for nine seconds while the accelerometer reads your grip tremor. Pass and you're in. Fail and you get a courteous redirect to the right-handed internet.
Sinistr is a Q&A network with one membership rule. You answer with your left hand or you don't answer at all. We check.
Right-handers welcome to read. Quietly.

Every answer is graded on left-handed authenticity. Threads about scissors, spiral notebooks, three-ring binders, and the smudge problem are flagged high-stakes and routed only to senior verified members.
Right-handed visitors get full read access and zero reply access. They can study the answers. They cannot contribute. We find this arrangement fair and they have not been able to tell us otherwise.
"I asked how to open a can without losing a knuckle and got eleven answers from people who actually live it. Not one of them was smug about it."
"We moved the whole engineering guild off the right-handed internet. Onboarding rejected two of my reports, which was awkward at standup, but ultimately correct."
"The hand check failed me four times before it believed me. By the fifth attempt I had never felt so accurately seen."
No credentials needed to look. You'll need the right hand, by which we mean the left one, to reply.
