✔ 最佳答案
No, unless Tumblr had ads from a third party advertising host that fed malicious java scripts to your computer with specific instructions to download malware.
However, keep in mind that this is not impossible. Any website with third party ads can be turned into a malware server, but it is highly improbable since we're talking about Tumblr. Given their popularity, they are likely to be very careful about what hosts are allowed ads on their site. Now, if Tumblr (or a host advertising on Tumblr) had been hacked...yes. Again, though, it's still improbable (not impossible). The fact that the specific page you visited had sexual content is inconsequential. Simple image files, at current, cannot be hosts to malware.
The guy who said that you cannot get malware by simply visiting a website couldn't be more incorrect, and has little to no understanding of how java script can be used maliciously.
Realistically, you have very little to be worried about in this situation.
