There are some information that needs to be revised such as:
1. Kingdice owner is not Kingdice anymore since it was bought by wetsuit (owner of freebitcoin). Reference: https://bitcointalk.org/index.php?topic=1637134.msg20064003#msg20064003
2. Owner/Admin of Bitsler can be replaced by Baryom which is more active in the forum.
3. SWCpoker is not opened in 2018, 2018 is just the new version/update to 3.0 of SWCpoker. I'm not quite sure when it was opened for the first time but it can be earlier than other sites as they were formerly known as Sealswithclub.
