Major update.
You can now verify the randomness was created fairly!
Just type /verify to the t.me/@bitcointarotbot

Randomness is based on a seed created by combining latest Blockheight Hash + UserId + Timestamp.

In your terminal, type:
node -e "
const crypto = require('crypto');
const seed = crypto.createHash('sha256')
.update('000000000000000000001393dd546c5e3ad8281bd161134a698bd15929afe3d9' + 'USER ID REDACTED' + '1773318801023')
.digest('hex');
console.log('Seed:', parseInt(seed.substring(0,8), 16));
"
And it will give you, in this case:
Seed: 1226359555

Which will correspond to your unique draw.
