A Bayes filter will catch things where the frequency of your tokens (characters or words) is different to the frequencies of the same tokens in a standard corpus.
In theory could be used for spam - your standard corpus is the set of good posts, you use tokens as words, and the whole thing is based on the assumption that some words or combinations of words appear more or less often in spam than in legitimate posts.
I suspect that some of the timeouts are associated with search activity on MS. These corresponded with @K.Dᴀᴠɪs posting a link to a search, which multiple people probably clicked on, and it took a considerable time to load. I've also had times when I've run long MS searches where people have reported timeouts here. This all may be somewhat coincidental, but it probably contributes to the overall loading on MS.
@Makyen I wonder if searches can be cached (for example, with the links). Maybe MS can create a copy link button with a ?cached=True argument that would prevent people who click the link from rerunning the search.
@K.Dᴀᴠɪs Almost always. For development, I have FIRE report AJAX errors. Delays in FIRE responsiveness are almost always associated with delays in responses from MS. Where it doesn't show anything, its almost always associated with the request timing out.
@Magisch Yeah, I've already added that to my list of things to implement. Providing no visual indication of the fact that the click was detected is confusing to users.
@SmokeDetector disregard. I've been having issues with my mouse double clicking things and I think it is clicking spam or something when I drag my mouse up >.<
