This weekend my Contact page got spammed. It’s now rewritten and using a few blacklists (including Akismet) among other techniques to eliminate spam. Should be much better now. I also think the handling of attachments should be better.
The spam appeared to be from a botnet, based on the fact that no 2 seemed to have the same IP address. So just blocking IP’s wasn’t an option.
Now things should be even better.
