Indeed, anyone can fork Bitcoin, but the Blocksize Wars in the past have taught us an important lesson. The decision of what Bitcoin is rests with the node runners, and it appears that the market has chosen to stay on the route that avoids the need for hard forks. While forks are technically possible, the current consensus favors maintaining the existing Bitcoin protocol making it backwards compatible which means significant changes are not likely.

I'm wary of going the moderation route - it's too subjective. I like the market based system of SN. In the spirit of Bitcoin, spam can be prevented by increasing the cost to post with each successive post. The cost can rise exponentially or polynomially in the number of posts without upvotes. If a post gets upvoted, then it won't add to your posting cost because the post has added value.

I guess this is not entirely secure against sybil attacks because a user can create multiple accounts to upvote their own posts. I forgot if there was an account creation fee, but if there was then that'd be a solution

I need to work harder on new memes.
I want to post them on SN Meme Monday contest, not because I would want the prize, but because I don't want the shitcoiners (copying memes) to earn the prize.

Only genuine and spontaneous memes with PoW should win.
I've seen SN accounts used only for that meme contest, they never post anything useful on SN...

Shitcoiners MUST PAY.
