If someone uses 2 different computers with 2 different IP addresses and 2 different email addresses, IHub wouldnot know that they are the same person....hence, maybe it can be done...
The trick is that if someone is going to do it, they need to be sure that they remember which name they are using...whomever posted those few posts, which clearly look to be from the same person, willnot, in my opinion ever get a job as a CIA operative or an undercover agent...LOL
Secondly, someone who would be doing that has something up their sleeve....
