Information:Spam

This is an information page.

It is not one of BattleIntelligence's policies or guidelines, but rather intends to describe some aspect(s) of BattleIntelligence's norms, customs, technicalities, or practices. It may reflect varying levels of consensus and vetting.

Summary

This page attempts to detail all of the current anti-SPAM measures the BattleIntelligence has in place, their effectiveness, and so on. BattleIntelligence SPAM has increased over time, and new anti-SPAM techniques are needed periodically to keep SPAM on the wiki under control.
