Sorry let me expand on the topic of this thread.
Sigil does not have an issue with database sites, so long as the data is collected through community members and not via data mining. (automatically sniffing and decoding packets. etc.)
We only have a ban on sites that are owned and operated by the Secondary Market (gold/plat sellers).
The negative impact is not from what they do, it is from who owns them and their interests in this industry. By going to any site that is owned by those who sell money in Vanguard you are supporting the sale and destruction of the server economies.
For example RPG Holdings, IGE, Zam Networks which includes Allakhazam, OGaming, WoWInterface.com, EQInterface.com, VGInterface.com, etc. are all owned and operated by the same individuals.
We will also not support any fansite that makes revenue from Secondary Market advertisements.
I hope that clarifies
