Re: [racket-users] Anyone successfully filtering Italian spam?

[Aidan Gauland]

I am on Fastmail, which uses SpamAssassin (their methodology is detailed 
here 
), 
and after many many months of training it on this loon's spam messages, 
it is finally /mostly/ filtering correctly.  Very few legitimate 
messages are getting sent to the spam bin now. (This is across multiple 
OSS mailing-lists.)


I hope this information helps somewhat.

Something has changed very recently because until this last week I
rarely saw it (even marked AS spam) ... maybe a few times this whole
year.  But in the last week I have gotten one or more copies in my
inbox
every day.

I use Thunderbird for email - which has a built-in learning junk
filter
- but I assumed my provider was filtering it because - sans a
specific
rule - Thunderbird would have just put in the Junk folder. I just
wasn't
seeing it.

I am gonna do this, actually, because i can see a few more words that are in pretty much 
all of the ones that actually get through my barriers. Judging by the google translation, 
it seems to consistently be a (very narrowly) "coherent" smear on the same 
people for the same things every time, and you have included some of the proper nouns, 
too, so this seems to be the way to go. I think it will get everything.

Thanks,

Nate



I've been dealing with this for well over 10 years reading various news 
groups.  You need to match on descriptive nouns: criminal, terrorist, 
etc.  Over time the names of the people and the descriptions of them 
will change.


If you look carefully at the Italian, you'll see the same descriptors 
come in multiple forms which change in use due to declension (parts of 
speech).  You need to match word stems rather than words:  e.g., crimi 
or crimin so you catch all the different forms of criminal .  Because 
the descriptors are nouns, you have to match them case insensitive, 
because they may or may not be capitalized depending on use.  The recent 
spam has been all caps, but that hasn't always been so.


Filtering can be done fairly easily with regex (with my NN reader has) 
once you figure out what to look for, but most email filter systems 
offer only a simple "contains" filter where you have to supply every 
possible capitalization (at least 3: none, all, and first).


Good Luck!
George

I am putting my simple sieve script here in case anyone is interested. I think 
it will get the stragglers, and the things in it, i think i have seen as 
constant for all the stragglers since i've first been getting it.

Sieve is funny because you have to look at like 5 RFCs to figure anything out 
from primary sources, and all of the third party non-rfc guides you can find 
from the search engines seem very limited so you kinda have to use the RFCs.

It's interesting, i think. It seems to me that the spammer is prefixing all of 
the proper nouns with hash symbol or something else. Maybe that is the reason 
the spam filters are having trouble, because they are not tokenizing the actual 
words, or treat hash tags specially, or something.

I think this person should teach a class on how to spam.

Unfortunately, this idiot has been spamming a number of (mostly 
programming language) groups for more than 10 years now.  Every other 
month or so the subject (and hence the relevant keywords) changes, along 
with the poster's name and email address, etc.


I used to read the racket groups through NN via Gmane ... sometimes 
still do, but mostly use email now.  A few years ago Gmane changed hands 
and got flaky for a while, so I activated email delivery on the racket 
group server to be sure I was seeing all the posts. Gmane still carries 
racket, but many of the other groups it used to carry are gone.


My NN reader has several filters dedicated to this italian spam, but 
(until recently) I didn't need to filter it from my email.

The last 10 spams have all these words in common:

and many more (which I won't copy here for obvious reasons).

So you could create a dedicated spam filter that looks for *any* of (not:

Something has changed very recently because until this last week I 
rarely saw it (even marked AS spam) ... maybe a few times this whole 
year.  But in the last week I have gotten one or more copies in my inbox

I use Thunderbird for email - which has a built-in learning junk filter 
- but I assumed my provider was filtering it because - sans a specific

['William J. Bowman' via Racket Users]

My spamassassin catches most of it, but also sometimes catches real list emails 
because it has stopped trusting racket-users. Some combination of bayes and 
txrep plugins are doing the heavy lifting, I think.
