it is my understanding that one of the main motivations of (some of the) spammers, is not so much the perceived traffic they will gain from their spams, but rather the search-engine rating they can gain by creating numerous links on numerous sites for the web-site they are advertising.
there is one simple, and, i think, effective way to reduce or eliminate this motivation:
Code: Select all
the rel='nofollow' as part of the <a ...> tells the search engines not to use this link for the rating of the site.
this simple step will eliminate a huge part of the motivation to spam.
of course, if this change is done as a MOD, it is practically useless, because the spammers do not know whether this mod is installed, so they will spam you anyway.
the only place this will be effective is in a new bbs system, and only if it is in the core code.
for all practical purposes olympus is a new bbs system, so, if olympus developers will incorporate this simple change into the core, olympus boards will suffer significantly less spamming that phpbb v2.
