It seems that one can only create a linkable hashtag when manually typing it in the textarea of the status box. In other words if you copy and paste them in or insert it via a JavaScript button, it's not linkable as seen here: https://peakfun.com/activity/stream/item/90

For minor issues I'm usually willing to throw my hands up if it creates too much fuss, however this is really important issue. If I can overcome this, I promise to share with everyone a really amazing addition to ES. Post categories! Basically I inject a list box (select) next to the share button that inserts a hashtag into the textarea. I could make it checkboxes if we wanted "multi-categories". In addition to this I'll give the code to insert pre-defined hashtags in the activity stream feeds list. This requires zero mods and will be ultra light (I spent a chunk of time today looking for the lightest way to pull it off). Having this ability to those who want it will enable all sorts of possibilities. From organized stream posts to photo contests, it would enable unification of important hashtags. Later down the road it could help with content filtering and make not only listing stream items/ES objects easier to view, but create better precision with finding specific content.

Back to the issue. So perhaps there is a way to have validation (could be client or server side) check for "#" followed by a word, and if it's not already a hashtag, force it to be one. I see that hashtags are wrapped in span tags, when attempting to copy it in the DOM inspector it shows a blank tag even though it technically exists in the DOM. This leads me to believe that the Hashtags on the client side are being stored in a hidden array (my assumption based on logic). Perhaps there is a way I could modify it to append new items? I can look into the how, but I need to know the name. I'm willing to do a lot of investigating for this.
