ASM claimed Dave Umansky was Weiss because he used the same user id on a Yahoo account that Weiss had on his AOL account. (garywbw)
Just looking at the NNTP posting host for Dave Umansky reveals it is different than for Brenda and Ted in the previous messages (just a few days prior).
NNTP-Posting-Host:
70.23.42.100
NNTP-Posting-Host:
news.jewish-usenet.org
The second one is very significant as it proves that NNTP Posting Host is a News Server
and not a Client Machine!
Note there are numerous public listings of Dave (and D.) Umansky's including some in NYC.
