I cannot speak on behalf of the mods running competitions, rewards there whether Heresy Awards or Rep are their call.
On the basis of awards in general though, with the growth of the site having slowed compared to a few years back, the userbase is providing less opportunity to hand them out. Things like serious thought provoking discussions, well planned and executed RP threads, and comprehensive tactical articles for example aren't cropping up like they used to.
Keep in mind, Heresy did have a system that allows users to request awards for other users, but this feature hadn't been used by anyone since 2013 and I think it's gone now. The mods cannot keep track of everything everywhere, and combing threads for award worthy content is a tedious task.
There have been several discussion on the matter weighing options, from abolishing them to resetting them to doing away with announcement threads and simply issuing awards on an as earned basis.
If there are rewards owing for competitions, let us know and show the relevant thread. Everything else I will simply say feel free to voice ideas but do not expect immediate change.
