Same here! I'm not a native English speaker, I live in the US but don't follow politics. I got a lot of Biden ones wrong because I haven't watched as many videos of him as Trump's videos. I also marked some real videos as fakes because I thought there is no way Biden or Trump would talk about this specific subject in this way.
Maybe we are missing some tricks to pick out the fakes.
For the majority of folks here who picked out the fakes easily, do you feel if you can do the same if the videos were of Putin speaking in Russian (with subtitles), or speaking in English with a very thick accent?
