Identical spam coming from many different (but similar) IP addresses
- by DisgruntledGoat
A forum I run has been the victim of spam user accounts recently - several accounts that have been registered and the profile fill with advertising/links. All of this is for the same company, or group of companies.
I deleted several accounts weeks ago and blocked some IP addresses, but today they have come back with the same spam. Every account has a different IP address, but they are all of the form 122.179.*.* or 122.169.*.*.
I am considering blocking those two IP ranges, but there are potentially thousands of IPs in that range. They appear to be assigned to India (although the spam is for an American company) so given the site is for a western, English-speaking audience maybe it doesn't matter. My questions:
How are they posting on so many IPs?
Is there likely to be a limit to the number of IPs they have access to?
Is there anything else I can do at the IP-level to block them? (I am looking into other measures like blocking usernames/links.)
