[Grammar] "And" or "or”?

[on the way]

[FONT=&quot] [/FONT]First, please have a look at the following sentence. "For example, we should not litter and spit or the garbage should be sorted.” Obviously, the "or” in the sentence should be replaced with “and”. But I wonder whether there is something wrong with the use of "and" in the sentence. In my knowledge, “or" is supposed to be used instead of "and" in this negative structure. Or "and" is also acceptable in this context? Any reply would be appreciated. Thank you all.

That is a sentence supposedly written by an unskilled English learner but actually intended for correction exercise as a drill in grammar for English learners whose native language is not English.

Thank you for your reply. Do you mean it is correct to say "We should not litter and spit."?

We should not litter (or) spit or forget to sort the garbage.
We should not litter (or) spit, and the garbage should be sorted.

Do you see the difference?

Thank you for your reply. I suppose the agent of the action "sort" in the second sentence could be someone else other than "we", couldn't it? Can the comma in the second sentence be omitted? Just to be sure, is it grammatically incorrect to say "We should not litter and spit"?

Possibly (see post #8).

But I think it's more likely that the speaker was trying to say We should not litter or spit ...
