I know that there is great envy and contempt for those who are members of the CM campaign, and dkbit98 is applied in same campaign few times (unsuccessful) just like his pal btcltcdigger - but that does not give them the right to call other signatures spammer
I honestly don't think that's the case here. Maybe it's just me, but his comment looked more like a tease than claiming you are just a signature spammer. People say that each other quite often here, especially when they have different opinion about something and if I am you I wouldn't give it a second thought, let alone make topic about such an irrelevant remark.
