I've never had a problem with them before either, but what's your definition of slow? I waited a week for my withdrawals, and I pm'd them, submitted tickets, pm'd mods, posted on the forums....they never responded to me....they still haven't responded to me. There's something different going on with them now. I don't know what it is but I hope they fix it.
Ah, well, it's a different experience for me. "Slow" is a 24-hour timeframe for BTC only recently but 3 years before that and 4 years of instant for LTC, ETH. I have gotten it fairly quickly (hours) once PM'ing. "Slow" was also last year; last one I did in May I believe was instant so had assumed they fixed it.
If it's true that there are week-long delays, I'm sure it's just a situation that's developed so an issue that needs responding. I know the owner has acknowledged the issue in the past when it started happening so let's see what comes out of this. Good luck.
