I think that steemit thinks that it is protecting the users by adding that little square that warns users that they are about to go out of steemit!
Thank you for this post, it is very useful - of course resteemed and I truly hope that steemit starts to pay attention to some things that are becoming not only annoying but very dangerous.
The most difficult to understand are the domains that have a little dot at the bottom of the letters (not sure how it is managed)...
I agree with all the points raised above and If I think about anything else I will make sure to add it here for further reference..
Steemit needs to take actions, perhaps a more detailed edition could be sent to steemit via utopian?
