Forum login changes?

[hameau]

It could be a forum spam plugin which prevents logging in with "inherited" cookies, maybe?

I'm fairly sure that it's a recent anti-spam measure, but there are at least two aspects to this:

• FF stored passwords is disabled by this site;
  
• the site's own persistent login feature ('Remember me') no longer works.
  

I'm very surprised that so few people are (apparently) affected.

Incidentally, the Wolf CMS forums are also based on punBB, integrated into the support site; I can still log in automatically there. Both sites serve a broadly similar market, so should attract similar levels of spam and nuisance posts. However, there are 967 registered members on wolfcms.org and little visible spam, 3.771 here and a rather visible spam presence. Now, 3.500+ plus members in two years (I think) on any specialist support forum seems like a lot.

Not a scientific comparison, but some informal dialogue between admins on the two sites might be useful ?
