This is not the first time that I saw one member having this kind of method, I reported it last month but I can't remember the user name, but thanks to LoyceV, we have proof that some members are using this trick.
It might be the user has many accounts and due to time constraints that he/she might not get the needed post count for his bounty at the end of the week, he simply put "reserve" in a hurry and then obviously come back to edit and put his supposedly thoughts about the discussion.
Just saw my name in this list and came to say hello.
I know I am not the case of this tricky, as many other users on the list such as nullius and Rose777 and other legit users here which are also on the list and not doing any tricky.
Personally, I never thought of using "Reserve" to tricky a campaign. There are many reasons someone might want to "reserve" a post.
And is that really a problem if a user uses this "tricky", writing "reserve" and edit it a few hours or days later? The post will be printed for eternity and the "reserve" only for a limited time... I think it may be good if the user can write it patiently and improve its quality.
Just my 2cc
