We'll soon roll out a new system intended to reward positive helpful posts in our forums, and to deter negativity.  Coding is complete and we are now testing in preparation for roll-out.  Once launched, we'll monitor the impact and feedback, and make adjustments as required.  The system works as follows:

- There are new buttons which will display next to forum posts, contribution comments, and commented contribution votes to rate the post positively or negatively.
- The option to rate posts is available for 72 hours since the original post, or since it was last edited.
- Rating posts is open to all paid user accounts, limited to 5 positive, 3 negative per day.
- You may monitor your rating via the My Profiler->Reputation page.
- User's rating scores will return to "normal" over time, in addition to the effects of updated user ratings.
- Positive reputations will display next to the user's name in forum posts.  Negative and neutral reputations will not display.
- There are four levels of negative reputations: Warning (no restrictions), Low (Limited to 20 posts per day), Lower (Limited to 10 posts per day), and Very Low (Temporarily blocked from posts, including contribution and voting).
- Posts edited by administrators are no longer eligible for ratings.
- Invelos admins will monitor rating submissions. Negative ratings without cause will be removed and may result in submitter rating reduction and/or rating permission removal.

Bear in mind that all restrictions caused by a low reputation are temporary, as the system automatically returns user's reputation score to normal over time.  The net impact is that no restriction lasts longer than 72 hours, unless impacted by further post evaluations.

Quoting goodguy:

This is problematic for threads where the first post is updated frequently to include new informations, e.g. for plugins or HTML sections announced and developed by forum members, link collections, etc.

Updated list above.

Posting restriction for a period of time is there, for very low reputations.  Additionally, note that contributions and contribution votes count towards those limits.
