find sb is doing sth 是错的，楼上回答的是两码事。
I find that ... 后面加什么作为宾语从句自然没啥关系。

你的提问 find sb doing 这句型中 sb 是宾语 只能是 me/you/him/her/them 这些受格或者特定人名，后面必定要跟动名词从句补充说明 sb 在干什么。

除了 find 之外，还有几个单词也具备同样性质，比如：catch, see, hear 等

例句：
She found Johnny cheating on his wife last week.
I saw him drinking myself.
You heard them discussing the trip, didn't you?
If you hurry you'll catch him walking out the door.

没有错。find (that) sb is doing that可以省略的 find sb doing 当然也正确

Find sb. doing sth 是对的

扩展阅读：find somebody to do ... be used to doing ... mind one s doing sth ... spend sb doing ... find sb do sth ... find sth adj ... spend sb to do ... find oneself doing ... find sb adj ...
