Did you seem to be right. But here there are so signature campaign can not stop spam. Although many articles have content suggestions but can it also for the purpose of spamming.
First off ask someone who speaks your language and speaks english better than you to translate. Second, I think you're saying that there are many signature campaigns , which in turn means more sig participants, which means more spam posts. Although you may be right, there are no clear steps on how to deal with spam campaigns, most are suggestions which can be gotten over easily and some are controversial and might harm forum itself: less traffic/ad revenues etc.
Sorry for the english is not my native language. Signature campaign is what motivates many people post. Right ?
They can write the article not to ourselves. Although it seems as constructive.
