"Heavily moderated" does it a huge disservice. The narrative is controlled, with any dissenting opinions removed and accounts banned. The sub is completely censored, see for example:
Except that all Blockstream projects are not only allowed, but promoted on r/bitcoin. If the subs own rules were followed they should be banned.
For example how Liquid, a centralized sidechain that goes against the idea of cryptocurrencies, is promoted as a "solution" to many of Bitcoins problems. But any critique of it is banned.
It's obvious that the mods are somehow associated with Blockstream. Only a Blockstream employee such as yourself would disagree.
