Whitelisting sounds good in theory but in the long run is likely something that would be really destructive to the community.

Reminds me of when SE decided to split the data centers. Some people complained that the community would suffer but most were willing to accept the trade-off for lower pings. So now all the JP that were on Sarga in 1.0 are gone and it really has made it less of a fun environment - at least for me.

At first not many people would whitelist but eventually everyone would and then the ability to connect with others is severely impaired.

If the real issue that people are upset about is spam from gilsellers, I would rather a way be found to more efficiently deal with spam. The OP doesn't really say why they want a whitelist for tells.
