This theory seems flawed. I see people who participate in the contests and pools we run posting on SN about other things all the time so it seems unlikely new users who stick around would just come to bet and if they do they do. People use platforms for what they like and want.

I respect your opinion that sports is a waste of time and betting is a waste of sats but people like it, so if it can help get more people into Bitcoin or on SN what is wrong with that? Should they be spending more time thinking about their freedom and the bitcoin circular economy sure but I believe in incremental progress rather than bashing people over the head until they comply or run away.
