There is a lot of spam from time to time. Is it possible to add better defense when register new accounts?
I agree... but we've (us frequent users/posters) been asking the same question for more than a decade. I wouldn't expect much action in the area of prevention from new accounts. If you think about it, those new accounts, even though of a one-time-use by spammers, used to be a part of the "membership" counts they advertised.
RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row. First step towards the paradigm shift of writing Set Based code: ________Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.

As an addition to Jonas' idea perhaps the reply needs to come from an account that has existed for a certain length of time and/or has a certain number of posts. That would stop them creating two spam accounts and using each to validate the other one?
I appreciate this may not be practical or possible to implement.
