I am not alone in finding it highly annoying when the dupe police come out in force or when a mod locks a thread from being a dupe. Not everyone browses arfcom the same way. The hardcore GD'rs stay in GD so they use arfcom by what is current in GD, then you have others who browse arfcom based on what topics are active then you have those like me who browse arfcom via Newest Topics so we can see other topics interesting such as the Tech sections where I also like to assist when I can. It is no secret the arfcom search function is in need of some work but more so we don't all create titles with the same keyword to search from making it no simple task to know if a thread is a duplicate.
Being logical about it, some visit during different times of the day so a thread created yesterday will not be bumped to the top in GD or Active listings thus inviting a new batch of users to participate in the thread topic.
It is my humble site suggestion and I will not be offended in the least if it does not align with Arfcom's idea of improvement, I appreciate the ear.
