1. First we need to define what is spam like what types of posts will be considered as spam. A proper guideline will help many people to improve themselves.
No.
2. Mega threads should be locked for not giving room to spammers.
Trashed*.
3. Most sig. campaigns enforce minimum post limits. This enforces people to write even they do not have enough points to write.
No.
New negative trust color:
Red color : Scammers Yellow color : Spammers
That seems like a rather *simple* change, that might just be effective enough. I'd be interested in hearing what others think about it.
Lets go one step further, don't call it trust, thats a marketplace thing. I dont necessarily distrust spammers, they are an annoyance.
Add a second way to rate users, call it
post score (or something similar), the system itself could even work the same way the trust system works (with only minor adjustments).
Might even add options to hide the post scores completely, if you do not care about that sort of governance/moderation.
While your suggestion is more advanced, and thus likely to be more useful, you are forgetting the simplicity of implementation. Adding another option to the current trust system should not be *too hard*. Implementing a whole separate system is, and I doubt theymos is going to do it given how little time he spends on this forum as is.

Horrible suggestion. Put that back into the garbage bin.
