The number of recent changes on the feeds was reduced to 10 from 50. You can thank some morons that have their RSS readers set to update at 5 second intervals for this.
Also, there were 3 IP bans added to the wiki today because of this. If you use an RSS reader to keep up with recent changes please do us the courtesy of setting it - at a MINIMUM - for 15 mins or more.
If this continues to be abused I'll just remove it altogether. Server loads were > 5x normal because of this. They normalized after implementing the htaccess Deny statement.
