It doesn't matter either way in my opinion. If people are going to troll or post shit applications, they will do so regardless if there is a post count or not. This won't change or help the matter any, the actual solution would be punishing people that post out of topic in those threads if the leaders have specifically said to keep it applications only and PM any questions, etc.
Some people just hate writing novels and honestly it's overkill to just join a lounge group. People have been trying to force people to basically write HUGE applications to get into groups for as long as I can remember. Especially when groups are asking simple questions that literally take a sentence to answer. The problem doesn't start there, it's a double edged sword. Just punish people more that use that section to troll and act like an idiot like the deal dispute section.
PS: You spelled "recruitment" wrong in your title.
