I think it can help avoid scammers.
A middle solution would be to increase the number of people able to see the ip addresses, like those in deafault trust and not just mods and admins.
Once again for N-th time
Nobody will see any ip adress or part of it.
As mentioned above we will see only if a and b use "same place" to post with certain probability of course.
Thea was my initial idea. Ck sugested geo ip part which does Something same but seems more "intrusive" for most of you
The best will be a simple number like trust next to nick
Something with +1 +2 and so on
For instance +1 means that there is one more account posting from same class c network.
What about it BadBear? That seems to keep the privacy and be a good start?
My initial idea with sql query results was the fastest way without spending time implementing new features and stuff
And when we see newbie with +10 next to nick opening a new thread with a single post saying something like I bought this and that from there and it works great all will be clear
Or have you heard about this and that advertising scams
