Thank you sheep2001.

I know 3 active members whose accounts have been deleted. None which I have deleted with 100% certainty.
I have deleted few newbies by accident.
I admid I have banned few accidentally, all which i have unbanned as soon as I've got message.
But yes recently there has been more spam by far.
And yes I have time, the wait time would be around few hours, less if I'm not working.
Manual activation takes less time than hunting the spam accounts afterwards. There is about 8-9 times more clear spam accounts semi-dormant than there is those that activly spam.
