I know that in some cases real customers were behind the registrations as I had contact with them and they register a second time with the same result! The steps they did then were exactly the same I did on my system ...
But I also can confirm spambot registrations if i check the tables in the light of your information.
The global site config on the live site is identical to the test site so I disabled the joomla registration. Will see if it improves.
Two questions remain:
- why didn't I had problems before CB 1.8 as the config doesn't change from my side?
- how can a user bypass the CB registration if there is no link on the website other than to the CB registration? (at least as far as i know)
Nevertheless, thanks to Beat, Nant and krileon for always fast and professional service!
