That last line "donate for luck" is increasingly common. People selling 'karma' or just asking for 'rain'.
I've tried to allow everything in the chat except for blatant spamming or advertising of competitors.
Should I be stricter and disallow begging for donations? Racism? Drug talk? Where do you draw the line? I don't know!
I personally think that begging in the form of (rain/karma/donation/budda/african children/...) should be banned after one warning. Between the nakowa 300 spam bets and incessant begging, it's increasingly harder to follow the intricacies of nuanced, rational discourse, investor moaning, and the merits of sparklecoin.
