Lemonade,
The site allows open registration. It is important that new and maybe inexperienced visitors find it easy and quick to make their first post. In the olden days you could post without registering. But we had to stop that because of abuse and the add it the Visual Confirmation and other traps to stop the spambots.
Fortuneately the level of abuse on the current policy is tolerable. I had to delete the first abusive pornlink poster since June this morning. We don't verify fake addresses because the professional spammers *all use* genuine email addresses nowadays and it adds in an extra verification step which may reduce new genuine members.
The use of multiple identities and unidentifiable nicknames is a tricky question. You might note I use 'Admin' when posting in administrative mode and '*****' when posting in a personal capacity. It sometimes helps if a person with a public role & name can sometimes post what they really think, instead of what they are supposed to think under a 'nom de plume'. STF will protect their real identity.
It all depends on you all posting sensibly most of the time. The more an Admin has to intervene, create new rules, procedures and checks - the less it becomes a relaxed, open and welcoming community.
What will not be tolerated is what is known as 'sock-puppetry'. That is the use of a name to post deceptively. I have banned a few occasions when the same person has been using two or more names to give apparent support to himself or to attack others and when banned people have re-registered. That's not a perfect science, sometimes its obvious, sometimes it isn't.
But good to have further evidence that Elvis is indeed alive and DIYing in South London

PS I am moving this from Town Hall to Town Asylum as it is a discussion on Forum Administration & Policy rather than Sydenham
