It would help if, when reporting new issues like this you explained what 
the actual problem is (such as "note 2401429 is a mere copy of note 
1230095").  Unfortunately on the issue here your report was instead just 
"SPAM".  You then (I presume after sending this email) explained the 
actual problem, and as soon as that was received the admins were alerted 
by the DWG member handling the issue to see if they could help.


However, as Mateusz has said, IP blocks are not effective, as most 
regular internet users won't have a fixed IP address (and anyone who 
wants not to be tracked by IP can ensure that every request is from a 
different one).  In some cases of unwanted notes it's possible to detect 
a problem note from content, but here that's not easy here because 
"detecting exactly the same contents as another note somewhere else" is 
(a) a computationally heavy task (b) will yield false positives and (c) 
is trivial to evade.


There will come a time, I suspect, when we no longer allow anonymous 
notes to be created in OSM (anonymous note comments are already 
blocked).  We already do get spammers (real spammers trying to advertise 
businesses, which this note adder in Brazil isn't) creating one account 
per edit.


Best Regards,

Andy (from the DWG)

To me https://www.openstreetmap.org/note/1230095#map=19/-22.97415/-43.33452
looks like a request to add unmapped restaurant (not spam) - why you closed it?

"2401429 is a mere copy of note 1230095"

In such notes note should and can be closed, I did this.

"Please block this IP" - note that IP blocks are not effective, it works only 
against dumb
spammers and affects also innocent people :(

[OSM-talk] SPAM notes in Brazil again

2020-10-27 Thread Erick de Oliveira Leal
Some time ago I reported that several anonymous SPAM notes were being
created in Brazil, through the "Report" option available in the note.
Someone told me it was not SPAM, so I showed the amount of notes in
sequence, so they blocked the IP of this account. But now they started
creating several SPAM notes again, I reported again and the user @mavl told
me that I should close the notes and not report them anymore, but the
"report SPAM" tool exists for that, if not to report SPAM cases , then it
should be removed from the selectable options. For example, note 2401429 is
a mere copy of note 1230095, another example: note 2401510 merely copies
the name of an existing element under it. All notes are sent in sequence,
anonymously, copying from non-anonymous notes or existing elements. Please
block this IP, it is getting in the way.
