You haven't asked anyone to remove their signature. Instead you left negative feedback based on an accusation.
As FJ said, their game provider canceled the bet and they are waiting for their response. You are jumping to conclusions. Also, I would appreciate it if you posted from your main account.
There is enough evidence in both threads to make conclusions. Please do a better rewriting while posting the same idea from multiple accounts.
Here is one more thread:
https://bitcointalk.org/index.php?topic=5118747.0 What will be your excuse this time?
Did you read the entire thread or just the topic title? That guy is making false claims without providing any for form of evidence. FJ Dice is provably fair, people who complain about it probably don't know how to verify the seeds.
EDIT: I'll be the first to delete my signature if some can show proper evidence of FJ being a scam. False claims, changes in their T&C or canceled bets by a third party game provider doesn't make them a scam.
