So, to summarize (and correct me if I got anything wrong):

• The website isn't profitable (yet)
• Deposits are working
• The website claims to pay a very high 12% APR on deposits
• The daily awards aren't always being added
• Withdrawals stopped working 5 days ago
• The signature campaign payments happen off-chain and thus can't be withdrawn now
• User whirlwindmoney hasn't been here for more than a month
• Support doesn't respond to inquiries

No matter what the reason is, this looks bad.
