Ok I haven't seen anything remotely resemble this idea. However if there is something like this, simply provide me with a link. Thanks.
Ok we all know how flagging works right?
You flag a message and it warns the mods which in return allows them to come and delete the spam comment.
Well how about have a lock flag. It could be right up near the title.
This handy dandy button could be used in a similar manner. People click it when there is a repeat/spam topic and it will warn the mods that it needs to be locked. Then the mods can visit the topic and see for themselves whether or not it needs to be.
This could cut back on the millions of billions of people that unconsciously spam when they say.. "Hey lock this mods," or the all popular.. "This should be locked."
I love this idea! I see so many topics that need to be locked, and this would help let the mods know without spamming myself and telling them that it needs to be locked. Also I haven't seen this idea before, so you're okay in that department.
