there are SMF mods for this. good lord. there are three in the OP
I'm pretty sure I totally misunderstood what you were talking about
I think I've actually talked to steve a little bit about it, but I'm not sure. in any case, it doesn't seem super plausible, you'd have to keep up with a number of likes for every single post people made, assuming people did use the extension. some older posts, in addition to new ones, as well. coding-wise, I think it'd be pretty simple, but the hard part would be the amount of disk space it could use, and maybe bandwidth
this really isn't that bad - think about it: the BLF itself has to store nearly 100x that information PER POST. one integer for one post? easy peasy. just store the topic id (in the url) with the message id, or maybe just the message id... not sure how SMF works, with an integer relating to how many likes there are - if it's +5. stuff, you don't even need a sign - just store 5. you know it's positive.
i've put some thought into this sort of a system, and since I don't have knowledge of sql databases i've never made it. after some thought just now though, you could probably do it via a pretty simple key+value database stored with loving text files and it'd still work ok. Redis or something.
this isn't hard to implement externally.
i did some work on this but then i realized i was way too loving lazy to actually implement any kind of spam protection or the webpage injection part of the tampermonkey script
