[Savannah-help-public] [sr #106304] Bug spam from logged in spammers?

[Sylvain Beucler]

Follow-up Comment #16, sr #106304 (project administration):

Some stats after 3 months 1/2:

-- * Approximation for anonymous spam + anonymous users who mistyped the
captcha *
-- User was not logged and check_value is wrong
153800
-- Idem, and in addition the posted text contains an HTTP link
147648
-- Validated post (captcha or authentified user)
8112 (=~ 5% of all captcha-filtered posts)
-- Posts per suspicious IP
min:   1
max-1: 8111  (77.91.229.56)
max:   12747 (208.70.78.16)
#IPs: 24946
-- Average posts by suspicious IP
5.3733
-- Posts per IP suspicious and per day
~ [1, 120]
-- Number of different IP adresses
28291
-- Average number of different apparently-spamming IP adresses per day
350

Beware: the messages we really need to analyse further are the 8000 ones, not
the 150000 others which are already blocked. So the analysis only confirms
that the spam we get comes from the clever spammers.
