I'd like to 2nd all three of the above suggestions. I've only been here a day and I know the platform is still in Beta, but the faster the platform moves to stop these things the better off the whole community will be. I have noticed the same and it only took me a day before I ran into all of the things mentioned above.

The faster these issues are addressed the more likely the integrity of the platform will remaining for future users and the project as a whole.
