We've been getting bots for a while that flat copy the text from other discussion sites and then edit the spam links in later. Usually you can pick them out based on the typical bot characteristics (vaguely real-sounding name, large bump or new thread about a very basic topic, slightly off-key or out of date questions etc).
Huh, that's been a thing? I mean, tbh, it did feel a bit off that someone would be lurking for 13 years since the release of the WiiWare version, now that you put it that way.
Apparently we also now have a profile post embed muncher so you can fill out the rest of this link if you want to see the original thread
