the site does exact matches only but is case insenstive.

Spot on

again, as the thread is getting long and I know from these posts that people arent reading it in completion

vBulletin accepts the form, sanity checks it
Passes control to the mod. The mod does tests against the remote database and if all tests come back negative, passes control back to vBulletin for its checks, captcha, dup usernames etc.

If there are multiple logs, its because the mod has passed it and vbulletin has rejected it. There is nothing that I can do about other than attempt to supress duplicate log entries, but then you dont see the whole picture.
