Sometimes yes, sometimes no. In practice, for example, webmail spam filters tend to be (virtually) culturally neutral because they&#x27;re driven by voting over large populations. In cases where someone writes a specific policy, yes, it will be culturally biased. That may be inevitable.<p>If you&#x27;re talking about email spam, then Tor blocks SMTP outbound, and big webmail services all treat send attempts from Tor with suspicion, so yeah you&#x27;d not see much direct SMTP spam from them.<p>And yes, Tor tends to already be blocked by any reasonable abuse filter, whereas the big networks are too-big-to-block, so that&#x27;s where spammers focus their efforts. But that&#x27;s why the big networks have full time outbound abuse teams (what I used to work on) and do spend significant sums of money on trying to keep their networks clean.<p>You can argue that they&#x27;re not doing enough, but when it comes to stuff like that, there is always more that can be done.
