You have to love the Internet as soon as you start getting enough traffic someone is trying to work out how to spam your system. It has just started happening on some swickis and I guess we will take it as a compliment that so many swickis are getting out there someone wants to hijack them.
The problem
What was happening is that people were repeatedly searching on a particular term in a swicki and clicking on their site in the results. Our automated system determined that the community found this term and site interesting and promoted it to the buzzcloud for all to see but often it was totally irrelevant to the users.
The solution
Now the moderator of a swicki can approve any changes to the tags in the buzzcloud. This is similar to the idea of having a blog with moderated vs. un-moderated comments. Click on "Manage Buzzcloud" from "My Swickis" page. Shortly you will have the option to receive emails to approve changes and be able to have your swicki totally unmoderated.
This change has the added benefit of letting the swicki owner know how it is being used, the terms people are searching for and how often they are searching. We are looking at adding more functionality like this as most swicki owners are probably unaware how many people are using them and what they are doing.
