I'm not absolutely sure what you mean by "hit and miss". Do you mean something like there were good days and bad days?
I mean, sometimes there were great posts, sometimes there were "OMG, this video, LOLz" posts, and sometimes there were splogs. It was largely an automated system, and some languages suffered worse than others.
What exactly means "temporarily"? Are you working on a solution at the moment and we'll see it return in some weeks or is it a bigger problem that takes more time?
The plan is to have something eventually, but it can't be what we had. The automated system just wasn't working. It needs either better filters, a more human touch, or some kind of magic. We're still still trying to figure out the whats and the hows.
Why haven't we been notified e.g. at modlook.wordpress.com when you disable a feature like this? This would help us answering possible upcoming questions in the international forums.
That was my fault entirely, sorry! I left the reply here and had a fit of OCD and went "Oooo, shiny!" somewhere else.
