I do not think that's applicable here. I think this woman was coerced into nonconsensual sex.
"Mean Girls" (five high school girls make up sexual assault allegations that they later admit were "because we didn't like him", school then did nothing to punish the girls): https://www.post-gazette.com/opinion/editorials/2018/10/15/A...
In the same hypothetical where character assassinations can be organized and bring someone down with false accusations, the same can be true of defending someone as well. Multiple people coordinating by speaking in defense of someone against accusations are just as possible.
I'd even speculate and say there's more instances of coordinated defense happening more often than false accusations, as powerful people being protected from accusations is what started MeToo
Edit: This is an honest question by the way. Thanks to those who did provide some examples.
