Solution

This will solve all of spammer-san's problems.

1. Deanonymize all of the /prog/'s posters from 2004-2010.
2. Track them down and capture them.
3. Bind and torture them.
4. Present them with a terminal only capable of posting on /prog/.
5. Permit them to eat only if they make posts that are similar to the ones they made during 2004-2010.

Consider this: A pack of egin gros.
Stupid, rampaging gros nearing your /prog/ board. >Trampling your blessed ground. lel. Defiling it with shit posts.
And you can't do shit since they outnumber you. They come. Their leader creates a thousand of threads and bumps them every day.
The shitposters finally dominate your board. lelLL. All is lost. They watch the resistance being crushed and you are forced to help them get doubles. LLLLEEEEEELLLLLLLLLLLLLL
Such is the downfall of LLLELLLLLLrider. >EGIN
