Difference between version and

At line 1 added one line
Fed up with the occasional spam attacks, I've written a Python script to undo changes from a given name or IP address, when using the VersioningFileProvider.
At line 3 added 137 lines
Its a bit convoluted, I've no time to make it better, but it may be of interest. You really should back up your pages directory, save the script as unspam.py and then run as\\
python unspam.py /pathto/pages.dir 61.145.233.118 \\
or\\
python unspam.py /pathto/pages.dir BadPersonName
You'll have to restart to clear the CachingProvider cache if you're using it.
