Every other day we are seeing someone spamming customer care number or something in korean and creating a lot of posts, making the forum very unsightly.
We can't expect mods to be online 24x7 to delete such posts and ban these spammers. Most of the mods are authors, or employees @webnovel, so they can't always manage the server.
So here's my simple, straightforward suggestion: Add timer.
Restrict the number of posts a user can make in a certain interval of time.
For e.g.: If I am making this post right now, put a timer on my account so I can't make another post in the next six hours.
This will prevent and discourage me from spamming irrelevant posts on the server.
...
Now, I know this is not a full solution for this because it can be easily bypassed if the spammer uses more than one userId, but, it's still better than doing nothing and waiting for the mods to delete. This is a prevention, not cure.
I hope this post does not sink in the tsunami of spam posts.
