May have banned user posting under diffrent account.

[huskermax]

So I have two users that were banned. I have a pay site. both of these users know each other. First one was banned started another account using his son's credit card but we matched up the ip to his old account.

The 2nd guy get's banned a few weeks later.

Have a new account set up, very active poster that posts just like the 2nd guy that is banned. All of my mods feel like it is the same guy. Different credit card and location then the 2nd banned guy.

IP's used are all local to the LA, California area. (2nd banned guy lives in Texas)

163.150.11.151 - CA (San Bernardino County Superintendent of Schools)
163.150.13.112 - same
163.150.22.112 - same
163.150.28.188 - same
66.74.192.130 - Twentynine Palms, CA
66.74.196.111 - Twentynine Palms, CA
10.80.127.201 - Unknown

The bolded one is new from the last few weeks. On the .com site I have been told this is a private ip address and this is one way a banned poster can beat the system.

I have the:

Proxy to Real IP Conversion

Multiple account login detector

These two have not triggered anything. Is there anything else out there I can use to maybe catch this guy?

If it is the same guy and he was using a desktop connection how would the ip be reordered?
