My main point here is I'm someone that surfs a lot more than I post most times a read multiple threads without making a single post and it became more often since I have to distribute merit. Now that simply means if I continue same way I'll probably be jr member in no time.... There are tons of members like this all over the forum.
No, I don't think you get him right here. Your activity and merits won't be alter if you don't make posts, it can only affect your merits after making ten posts without earning at least a single merit. As good as this sounds, I don't think it's the perfect way to combat spam, it would rather give more room to merits selling.
There is a campaign manager that make it as a requirement to earn a merit in every week you participate in his campaign in order to retain your slot. For once, I never noticed a participant was removed for failing to meet up with that requirement. People can always find their way out as long as its merit related. We can think of other alternatives but this particular one seems to be defeated imo.
