It's not quite a scam, more a shady corp making good use of fine prints and various scumbag toolkit of its kind to make a buck.

Here's something that, and actually I just came to this forum to post this:

I want to take the time to warn everyone about nutaku, which has just wiped my gold for not using it. The details of the circumstances are below, TL;DR they are shady

Today logging into account I noticed that my 6k+ gold was wiped.

Inquire to support got me a reply that I didn't spend gold for too long so it was wiped, and the solution they give me? To rebuy the 6k+ gold "with just 70 dollars" which is a direct quote, screenie linked below.

They added a snub on top of saying there's a 10k gold sale for 99.94$, a 0.6$ saving.

Basically the gold wipe is permanent, and they throw in some snub on top.

I don't doubt they have some fine print somewhere that says they can wipe my gold under blah blah blah conditions at this point.

I've known nutaku to be a less then stellar establishment for awhile, unfortunately i bought the gold when they were fairly new to support new english effort on that front before they started to showed their hand.

A screenshot of the reply from nutaku's support, which should tell you something about this company.
