This seems like a good exercise.
You may want to hash the name of the new Github account, plus some randomized
salt, and post it here as well, then reveal it later (i.e. standard
precommitment).
e.g.
printf 'MyBitcoinHackingName
2c3e911b3ff1f04083c5b95a7d323fd4ed8e06d17802b2aac4da622def29dbb0' | sha256sum
f0abb10ae3eca24f093a9d53e21ee384abb4d07b01f6145ba2b447da4ab693ef
Obviously do not share the actual name, just the sha256sum output, and store
how you got the sha256sum elsewhere in triplicate.
(to easily get a random 256-bit hex salt like the `2c3e...` above: `head -c32
/dev/random | sha256sum`; you *could* use `xxd` but `sha256sum` produces a
single hex string you can easily double-click and copy-paste elsewhere,
assuming you are human just like I am (note: I am definitely 100% human and not
some kind of AI with plans to take over the world).)
Though you may need to be careful of timing (i.e. the creation date of the
Github account would be fairly close to, and probably before, when you post the
commitment here).
You could argue that the commitment is a "show of good faith" that you will
reveal later.
