We've got something important that we need to share:
A malicious user send fake delegation links to steem accounts via our withdrawal feature with a custom memo.
If you have received such a link: don't enter it in your browser! This was not us!
There was also no breach in our system, everything is secure.
The responsible account has been blocked and blacklisted from our service and we've gone ahead and disabled custom memo's for now. We've also send a transfer, warning users, to those who received the dubious link in the first place.
But fear not: everybody is still able to purchase discounted SteemMonsters packs via withdrawal, however, we will only allow custom memos in individual cases.
The account: 
We have only 3 different accounts:
Only those, no others!
To close this post up:
We will never give into scammers!
And scamming will never be as lucrative and fruitful as doing things the right way. Doing things the right way is always better!
Sincerely ,
Team Smartsteem
