Definitely; I would encourage everyone to report "reserved" posts or ones with ellipses (og kush420 didn't even write a full ellipsis, just two periods, lol) to the mods.
Certainly we can report such reserved posts, even if they were edited mins or hours later.
Assume they return and edit such posts a few hours later, it is off-context. Because that discussion should go beyond the one happened around that reserved post. I don't say it is off-topic but off-context. Another minus point is edited content is always low or zero value, shit posts indeed.
I realize this is probably just one campaign we're talking about here (1xbit)
1xbit and Stake.com campaigns. However, I don't aim at any specific campaign here. It is probably more posters like that and matter is we did not detect them.
