[A riddle I created that I honestly have forgot the answer to! :/]

Replace the "m" with a "b" and I become hair on a mans face, remove the "s" I'll be rolling, put me back together and I may nearly fall.

Hi guys,

Firstly, let me introduce myself, my name is Bledfordays and I am co-founder of the website "riddlewot".
Some of you may already have heard of us, for those who haven't... we first went viral in 2015 after the popular youtube channel Vsauce showcased our site in one of their videos... we then gained more success due to posts on both reddit and metafilter. Over the years the website has changed design and concepts many times and while we thought we were making improvements, looking back, our quest for perfection almost ruined what we'd created.

I'm extremely happy to announce after many months of re-writing code, riddlewot has returned to its original glory! 
We definitely don't want this to come across as a spam post. If it's something you might be interested in, feel free to check us out, otherwise thank you for reading.
