- Why CBV?
- Usually, if a Sysop wants to run a reasonable BBS, he or she
- must implement some sort of security and a way of double-checking, or
- verifying new users so that each account on the BBS belongs to one
- real person, and each person has only one account.
- The popular method of security and verification is set up so
- that new users have restricted access to the system (usually new users
- aren't allowed to post public messages, upload, and download). The
- sysop calls the phone number that the new user entered. If all goes
- well, the number checks out and the Sysop gives the user normal membership
- access. The conversation is usually a pleasant experience for both
- the sysop and the new user, and the Sysop can check for duplicate
- numbers in the event a user tries to gain more than one membership.
- Unfortunately, some users call and leave bad phone numbers.
- It doesn't matter whether the user is hoping to join the system
- without the sysop trying the bad number or is just trying to annoy the
- sysop. Either way, it is just wasted time on the sysop's part. This
- is usually what happens first on a younger BBS.
- After a while, these "twits" start trying other tactics. They
- pick a name and number at random out of the phone book, then they log
- in as a new user using this false name and number, but the number is
- "good" in that it matches up with a real live person. It can fool
- some sysops that only check the phone book to match up the name and
- number, but for most sysops who actually call the numbers, a huge
- misunderstanding may take place between a soon-to-be-frustrated sysop
- and a confused innocent person who usually doesn't have anything to do
- with computers.
- Yet another strategy appears. The new user logs in and makes
- up, or even worse, looks up a long-distance phone number. Some sysops
- make it standard new user policy to call the number collect. You can
- imagine the misunderstanding that often takes place! Other sysops
- call with their own money only to find they've wasted fifty cents on
- one of a long list of bad long-distance phone numbers.
- As if all this isn't enough trouble, even many of the valid
- numbers can add to the problem. Often nobody is home at the number or
- the number is constantly busy.
- All this calling about, wrong numbers, no-answers, and busy
- signals add up to quite a bit of time if not money wasted on wrong
- long-distance numbers. Not to mention the honest users that have to
- pay by waiting and waiting for the sometimes discouraged sysop to
- finally get around to trying their number.
- So what's the burnt-out sysop to do, short of pulling the
- plug? Many do just that when things start getting bad. Automated
- Call-Back Verification offers an alternative - It's instant, rarely
- requires sysop intervention, relatively painless (maybe even pleasant),
- and it keeps the modem-scum out!
