We have seen blogs faking feedburner subscriber count by displaying someone else feed button, now thenextweb shows a way to increase subscriber count overnight to whatever number you want, think of thousands.
It is easy to hack the feedburner count. All you need is a netvibes account to boost subscriber count.
This may be a bug in Netvibes counting of the subscriber numbers, or may be a feedburner. Hopefully it will be fixed soon either by Google or netvibes, don’t fake your subscriber count in the mean time. Via Webware
