Until recently, ScrapeBox has been offline due to DDoS attacks. The servers are offline as I write - presumably for the same reason. My understanding was that ScrapeBox had put some counter measures in place and updated the software - but presumably the attacker found another vector to shut the servers down again. Stay tuned... hopefully soon -
This seems to be on on going issue for now, this happned to me a last week, and I was down for like 3 or 4 days. My advice is to just keep SB open if you can.
