was just wondering about the recent number of forum guests (1215) - perhaps it was a bug. normally the number is around 100, now it is normal again...

@Jona Usually happens at the weekend. I wondered about that too.
I deleted 3-4 thousand users last year...... with strange auto generated x.y.z addresses...... worst.txt
It took about 6 days.
We have quite a few new users with gmail accounts not posting and not returning.
I considered deleting them after say 4 months.
It's a lot of work but maybe worthwhile.

But as they have not returned I don't see how it can be a DOS attempt.
Otherwise...... I wonder if it happens when a robot (google etc.) scrapes the site.
