New update.
Update looks great. Spyke has arrived with a bang. It is fresh and full of fragrance. The team is self made, innovative and enthusiastic. They are very receptive to suggestions from the users. Support and encouragement from the users will go a long way to mature Spyke for ultimate satisfaction of the users.

Any way to post with spoiler like it hides a text or image
Whenever you open the comment text box, there's a link on the bottom to a page that explains formatting. It says "Did you know you can style text using markdown? Learn how"
By that page, it would seem that there isn't a way to spoiler text by default.
