i was able to get a temporary solution to my problem by editing vftpd.conf and blocking everyone apart from those on the user_list, these brought down the number of forced ftp attempts to zero on the server for the last 4 days, but i do believe i will still have the same problem if a bot tried to log in with a valid username.
So in the meantime i will try to find a regex to do the job properly. Thanks all.
Any help will still be appreciated in finding a better regex.
