I'm quite new here so perhaps this happens more often but I noticed suddenly that lot's of questions are being asked on OpenEBS from new users (<10 reputation). Their names make me believe they're from India or so, at least all from the same region. Is this spam or is this more common in September when a new school year starts or ...?
You are definitely on to something. If you search for "OpenEBS", you will find only a dozen and half or so questions, but almost all of them from new users opening a "new" account in the last 8-10 days.
If you look at those user's posts in StackOverflow, you will see that each new user is dropping a barrage of questions and they are all on "OpenEBS."
Somebody is definitely running a scheme to promote OpenEBS. OpenEBS, by the way, is developed and ran out of India, and looking for funding.
