They use many IP addresses (possibly via a Botnet) and are able to elude the captcha and advanced questions asked on sign-up (what is the square root of 144), as if they manage to sign-up via a proxy or IP addresses or devices where that bypass the captcha / sign-up questions.
However, they are easy to catch:
I hope this helps you get rid of them.
Seeing those too! Thanks for the overview!
We are receiving oddball spammers again as well. Just now from "Passaic
MM" with odd email
Luckily our sign up questions are tip off to deny but yes, it seems they've begun again. Augh
Kos that is right, exactly the spammers that are showing up although they do not spam on my community as every member pends first then I simply ban them before they even get in. BUT I grab their IP and place that in the sign-in block area.
Yep, the minute u see those . dot.dot dot . email addresses you know they're crap. *lol* Received 3 more this morning (hairstyles). Uh, no thank you. *bam* I wonder how much they're paid to be so annoying? Maybe I'm in the wrong line of work. LOL
How are they spamming? Profile comments? Forum spam? Friending and then private messages?
Thanks for the heads up!
A few of them manage to make it through the sign-up process, because I have so many new members to approve each day and so little time, my brain makes a rejection decision in 0.1 second (I hope it could be automated).
What I've found is the following:
They want to post blog posts, promoting diets and pills to lose weight. Thanks God, I also have to approve each post and thus they actually never went live. I don't understand why they continue to hit me so hard (about 10 new sign-up attempts each day) since they are not getting any benefit out of it. Not even one blog post that lasts more than 10 minutes. They must be using a Botnet.
Not sure if they do email spam or profile spams, and never heard a complaint from members, and I have seen anything in my various decoy accounts. Note that they can't send an email blast to any of our groups: this email blast option was turned off by me long ago, due to abuse by spammers.
Can you tell me(us) more about decoy accounts. I would like to see exactly what my members see and know exactly what they can do, especially inside of private groups for example. I don't know how to set one up however. Do you need permission from Ning?
I've had 50 in the last 3 weeks from this crew. On my site they post advertising material in blog posts. I have set my controls to "approve blog posts before they appear" and this seems to stop publication nicely. Every day I go to blog moderation and delete their profiles for SPAM and ban their IP addresses and everyday I get a few more. It takes a minute or two each day.
I too suspect that they're spambots avoiding signup controls and they're indiscriminate in the sites they're targetting. None of the spam ads have relevant offers for my country or my audience but they appear regardless.
Some of the recurring email addresses come from:
We have been hit the last few days as well. Unfortunately one did get past and he had a decent profile...answered all of the questions with lots of information. The first attacks were from Accra, Africa and today we got one from India. I have taken the time to trace all of the IP addresses (the block of...) issued to them and once I banned all the IP addresses associated with them the sign ups stopped. The ones we have been getting are not using the ma.ry.ca e-mail addresses but firstname.lastname@example.org.
Here are the IP addresses if you wish to add them to your banned IP address list~
The 212 IP's are from Accra, Ghana
Now wouldn't it be nice if we could bulk upload these IP's?
Sure would...or to have an auto IP ban list incorporated Ning wide ~ :)
I know right? How about IP approval added to spam watchlist! A feature that would never work otherwise.
