Turns out, they were truly just under maintenance. With that said, I've been more wary of drugwars recently, not because I think they will scam its users, but because the development has not been smooth sailing. Their StateoftheDapps profile also said that they are no longer a Steem Dapp. So, while they are not a scam, there is still the chance that they will exit the Steem Blockchain and move elsewhere. I hope they don't though.
