ProZ.com site rules govern the use of and participation in the various site areas, including KudoZ: http://www.proz.com/rules/
One of these rules, http://www.proz.com/siterules/general/8#8 , states:
Discussion of administrative actions taken by moderators or site staff should be carried out solely via the site's online support system. Administrative actions include rules enforcement actions in the forums and KudoZ, warnings or restrictions on posting or other rights, editorial adjustments to topic subject lines, the locking of certain forum threads, selection of topics to be featured on the home page, etc.
On the subject of "censorship", let me quote FAQ
http://www.proz.com/faq/5651#5651 , which was written for the forums but which can be applied to ProZ.com in general:
What about freedom of speech? There should not be censorship in the forums.
The forums are limited in scope and subject to rules. It is important to know that the site rules and scope have been in place for some time now, and they are there and enforced precisely in the interest of maintaining a positive, results-oriented workplace. The only way for this to happen is for those rules and the scope to be enforced consistently, and that is what moderators and site staff do.
This said, it should be noted that, within the framework of site rules and the aim of those rules, not everyone is going to be able to say whatever they want at ProZ.com. Keeping a positive, results-oriented translation workplace means that posters will not be able to swear, or to talk politics, or make offensive remarks in the forums, for example. There are other places to do that. Everyone has valid opinions, views and statements; but it should not be assumed that ProZ.com can be used to advertise these.
If you feel you have received rules enforcement action which was not rules-based, please report this to site staff through the support system, where the issue can be properly reviewed. The forums are not an appropriate channel for discussing individual rules enforcement issues.
If you feel the application of site rules has been inconsistent, please report this via the support system, where site staff may appropriately investigate and react where necessary. I'm closing this thread, to allow discussion of this to go through the proper channel-- the support system.
