I recently received a memo message for a "survey" from an account with no post or comment history asking me to go to a website with a Hive-related name. It seems to be starting on accounts with the letter A so thought I'd get this message out before it reaches many others.
Be very careful with clicking on unknown links from accounts with no history or reputation on chain. This is a sure way to get your keys stolen and account hacked and that's the case most of the time with these that come out of nowhere.
I'm not going to link to the account here but I'm sure it's not that hard to find it based on my first paragraph, but I suggest you don't and just warn others about it.
It's very cheap to send mass-links to Hive accounts since it only costs 0.001 Hive to send a memo with a large message and you need not that much Hive Power or RC delegation to send out a lot of them. 100 Hive would be enough to send to 100,000 accounts and for these hackers it's enough that they manage to steal funds from a few accounts to profit off of that activity.
Anyway, that's it. I'd prefer not to have to spend more time trying to recover people's accounts due to things like this and have brought up this issue with others in the past to figure out ways to mute accounts with suspicious/potentially harmful activity such as this from front-ends.
