There is a frooferall happening on Twitter about a conference where all the organizers and all the speakers are male.

I would like to make an offer to all men doing mediocre research in STEM fields: If you pay for my registration and travel, I will be your conference beard. I am smart enough that with a few months of effort, I should be able to contribute to your mediocre research in a sufficiently substantive way to be considered a co-author. And then you can submit the work as joint with me and tell the organizers that I would be giving the talk. And since I am a mathematcian, I expect the names on the paper to be listed in alphabetical order, so if your last name begins with A - SY, then you would be first author. And you would get to be a hero for the organization by sparing them from the embarrassment of having an all-male speaker line-up.
