In the summer, I had an incident with another member, and I contacted the admin, and I think they responded a few hours later.
But, sometimes, they take a long time because they're simply just busy! Don't take it personally.
It depends who you contact; what for; if it was dealt with before we saw the message; if it needs to be discussed with other staff before we take action; what is happening in our own lives; etc. If you contacted LaBelleFleur or Murray they're both on vacation right now.
Scam complaints often do take a little longer for us to get back to on because we need to research the case and try to establish contact with the other party to hear their side of the story before we can take action on it.
