Because of the spam problem, it is a multi-faceted problem, so the solution to spam needs to be done from all factors.

Spam is mostly found in comments ([Econimics]), ([Bitcoin Discussion]) and ([Meta]) This is not surprising, because the free center-based ([Forum Bitcointalk]) also always receives dozens of spam comments every day. Much more - many times more than the original comment.

Therefore it is very necessary in this case:

<> (Filtering):
Examples of one way from technical-based tips. Filtering will not be a complete problem factor, it only helps alleviate spam. Although filtered, the total amount of spam that actually enters every day continues to increase.

<> (non - technical):
which is fundamental in handling spam, and can reduce spam, especially from new high-class players who are passed on to beginners.

I conclude Even though have done various ways / things, in handling spam, every day incessantly continues to be a trick that is widely practiced in this world without being realized, either on Meta or in Local.
