We'll never get rid of ALL spam. We keep reporting because at this time it's the best we can do to make the forum cleaner, even if a little bit. We can also use merits for some positive incentive. If theymos comes up with other tools for us to use we'll do that too (sounds a bit brown-nosy but he is the dictator of the forum so what else can we do other than convert all our BTC into BCH and leave).
