Random spam isn't for things like "jnsildfbilsdbbjbjopaoHohsoa:soJpjSjsLih" It's for threads like these (They aren't actually clickable) eb.archive.org/web/20130530161321/http://itsjerryandharry.com/forums/forumdisplay.php?fid=24
But there's no reason why people can't post things like "jnsildfbilsdbbjbjopaoHohsoa:soJpjSjsLih" After all, it is random spam.
I completely agree. Just because this is random spam doesn't mean you can spam the shit out of the forums. The threads need to have some meaning.
