killer_engine: Social spam
Spreading beyond the centrally
managed social networking
platforms, user-generated
content increasingly appears on
business, government, and
nonprofit websites worldwide.
Fake accounts and comments
planted by computers
programmed to issue social
spam can infiltrate these
websites.[11] Well-meaning and
malicious human users can break
websites' policies by submitting
profanity,[12] insults,[13] hate
speech, and violent messages.
Online game messaging
Many online games allow players
to contact each other via player-
to-player messaging, chat rooms,
or public discussion areas. What
qualifies as spam varies from
game to game, but usually this
term applies to all forms of
message flooding, violating the
terms of service contract for the
website. This is particularly
common in MMORPGs where the
spammers are trying to sell
game-related "items" for real-
world money, chiefly among
them being in-game currency.
Spam targeting search engines
(spamdexing)
Main article: Spamdexing
Spamdexing (a portmanteau of
spamming and indexing) refers
to a practice on the World Wide
Web of modifying HTML pages to
increase the chances of them
being placed high on search
engine relevancy lists. These sites
use "black hat search engine
optimization (SEO) techniques" to
deliberately manipulate their
rank in search engines. Many
modern search engines modified
their search algorithms to try to
exclude web pages utilizing
spamdexing tactics. For example,
the search bots will detect
repeated keywords as spamming
by using a grammar analysis. If a
website owner is found to have
spammed the webpage to falsely
increase its page rank, the
website may be penalized by
search engines.
