It's very common to see new members join, then immediately startpostingspamming the crap out of forums with pointless posts, and bringing back topics from the past, many of which have already been resolved.
What's more maddening is they do it immediately after joining, not knowing the time-in-rank restriction (6 days) on top of post count. So the spam is futile, even if the moderators let them slide.
It greatly annoys me (and I'm certain many other cK users too, do y'all?) to be flooded with notifications of these new posts, or just be lost in what's going on from it.
Some of them are trolls that deserve to be banned, but I believe most of them are just misguided:
1. Not extremely fluent in English, or
2. Younger users who have yet to know the impact of their actions.
They shouldn't be banned, but I think there should definitely be:
A. restrictions on their posting ability (at least in the first 24 hours or something like that), and/or
B. an auto-PM detailing this, or
C. a redirect to a rules topic
-though due to their lack of patience and possible limitation in English, a separate, shorter topic with just this info may stir their attention better. Throwing the whole rule list may deter them from reading.
For B. and C. to be effective though, the title of the PM or topic would have to really catch their eyes, like, "YOU'RE BANNED", or "READ OR RISK BEING BANNED", in big, and in red. Since they're already too lazy to read the rules, only something with a shock value like that would grab their attention. From personal experience, a formal title like "Welcome. Please read." just leads to it being ignored, especially if the message becomes a long block of text.
Though many of these spam posts are empty, I do see at least some of these spammers putting thought into their responses, even if they're not necessary (like their own opinions and advice on an already-solved past problem, for instance). It's a shame that they are sometimes punished as a result; they had good intentions, just poor execution.
