[Pmwiki-users] spammers - using a wheel that has been invented

[Pierre Rouzeau]

Hello,

The blackword maybe simply be a sufficient number of  'http:'  references ?

How many links is it legitimate to add in one time to a page ?
2, 3, probably not more.
Even when maintaining my link page, i rarely, if ever, have added  more 
than 3 addresses in one time, except when i created the page....

So a possible behaviour can be :
. Count the 'http:' references in the original page.
. When page save is asked, count the number of  'http:' references *added*:
a/ if less than 3 addresses are added, allow the page saving
b/ if between 3 and 8 addresses have been added :
   -  do not save the page (so no history...)
   -  give the author a link  to a page which will explain the limit 
(create minimal difficulties to get the info, sort of..).
   -  blacklist the IP address of the author for 8 hours (say, no edit 
right at all during this period).
    - Record the  IP address somewhere, alongside the added 'http:'  
count number

c/  if over 8 addresses have been added :
   -  Do not save the page, *no* warning
   -  Blacklist the IP address of the author for 8 hours.
    - Record the  IP address somewhere, alongside the added 'http:'  
count number

And if a reverse lookup on the IP address can be done, that might be a 
plus for the record.

There must exists a special procedure to allow link pages to be created
1/ Having entered the admin password...
2/ Another solution is to create a special markup, say :
   (:links:)
 [=
   :site1.com
   :site2.net
   :site3.org
   :site4.fi
=]
Which can be validated by the admin later (make a special call in the 
mailpost ?)

Regards
