In article <nnd$5de7d841$38faa047@db6835260754ed96>,
I usually read Usenet newsgroups via
new.eternal-september.org and
only very seldomly see a spam message in the comp.lang.ada newsgroup.
However, occasionally I check this newsgroup via Google Groups,
and there the last several weeks the amount of spam has increased
tremendously: indeed, several hundred a day!
For some time I have reported all of those as abuse.
When doing that Google claims:
"Google takes abuse of its services very seriously. We're committed
to dealing with such abuse according to the laws in your country of
residence. When you submit a report, we'll investigate it and take
the appropriate action. We'll get back to you only if we require
additional details or have more information to share."
But I haven't seen any impact, nor did I get any feedback.
So I guess only 2 ways remain to address this problem: either use a
newsreader that has sufficient "kill features" to junk most of those
spam messages, or switch to a newsserver that uses sophisticated
enough techniques to not distribute such spam in the first place.
