ATTENTION

Repeat after me: I will never, ever, ever use any website to generate my seed

Recently, multiple users posted that their iotas were stolen. Some of them seemingly used websites to generate their seed, like iotaseed.co or iotaseed.net. (iotaseed.io might be legit or not)
It should be clear as daylight, this is crypto 1x1: Never use any website to generate your seed.
You don't know what code is running in the background of the website? Don't use it. It will almost certainly try to steal your seed.
