Duplicate title/ duplicate description results show up. But i really not sure if this will lead to a ban too.
Not at all likely.
algorithmic <<- also lead to entire index gone completely ? or just SE ranking drop.
Almost always an algorithmic drop. Complete bans are quite rare today - the site need to be seen as extremely abusive for a ban to happen. Something like being part of a large backlink scheme, doing deceptive cloaking, something like that.
