One #monal user came today: "Your chat went crazy!"
He showed me his iphone: the screen was flickering.
I checked prosody logs. Nothing.
I looked at the screen again and got what happened.
A day ago I sent three links to that user. Monal tried to get a preview but the site kicked back with antibot protection.
Instead of displaying something sane Monal seemed to retry without any delay that caused flickering.
I keep myself calm.
I keep myself calm.
I keep myself calm.
