I am pretty sure your funds are safe.
This admin is just very slow to respond to tickets. Basically it has been like this for years.
If you read back a few pages the motto for this site is "Its called SAFEdice because due to your funds being stuck... they are safe from being gambled".
I've commented on this thread a bunch of times, commanding the admin to hire someone to direct support - even part time. Because every few days or so, there is some issue that doesn't get addressed for days and days and people start calling it a scam since they don't get a reply.
I don't know but this is the first time I have seen SafeDice down for this long, they should have at least have a support staff updating the status of the website in order to keep their members' minds at bay. By the way did SafeDice replied to your suggestion? Because even if they did I don't think they have added any additional staff in their casino. What SD is doing with slow withdrawals and long down times is making them have more dissatisfied customers which will eventually be leaving the gambling site for good.
