And then what? Half the time that causes the thread to be remade. Sometimes many more times. And the battle continues with the next and the next thread getting spammed. Whereas a lot of these threads will fall of the board (sometimes with a little help) if nobody spams in them.
If we don't want bad threads, we need to get the people making the bad threads to leave, and they won't do that while somebody's entertaining them with a spam war. It would be excruciatingly boring to manually bump shitty threads for days on end without getting a reaction. The spam is the main reaction nowadays.
I realize you're not the spammer, but I'm hoping he reads this.
