What if I wanted to hide all posts by a member (Change visible from 1 to 2?)

[Quarterbore]

I have a member that I may want to hide all of their posts in a temporary way in case the member comes back and askes for their posts to become visable again....

I am curious if I would be making a huge mistake if I go through and execute a mysql command in the posts table such that when post[userid]='1' make post[visible]='2' in the database?

I know enough to try this on a developmental board first!

I hope that I could undo this later by going through and performing the opposite if the member wants their posts back on the forums later (IE change visible back to '1')

Would this cause me problems?
