Scammer On Instructables!
Going by the username of 'soukayna', they will have no profile picture. Clicking on their profile will show that they claim to be a 24 year old female. They'll send you a message via orangeboard or PM reading thus:
"Nice To Meet You My name is Favor, i saw your profile and it drew my attention to write to you. I would like you to communicate me through my e-mail address (email@example.com)so that we can get to know more about each other more and also to exchange our pictures. I am waiting to her from you. until then continue to be blessed. Favor"
A quick google search on the alleged "Favor Madi" revealed that they've posted this scam on several websites. The best thing you can do is immediately delete their comment. If anyone knows a way of reporting them to the instructables site, please do so.
It's dissapointing to me that the first comment on my orangeboard was a scam.
