In my opinion, there are two possibilities when it comes to Lidl Drip.
1. Dyn sock. (This is the one I believe, and I will elaborate.)
2. Woman who copies what Dyn does because she saw how close he is to Null and wants to be like that too.
The reason I believe Lidl Drip is Dyn dates back to the 2019 Kiwifarms leak. Dyn did eventually leave over it, around February as far as I can tell. He would not publicly rejoin Kiwifarms until October of that year, but February sounds a bit familiar, doesn't it?
I think that the Lidl Drip account was created by Dyn back when he left so he could continue lurking KF, since he was (and still is) addicted to it. He then made the account he currently uses and discontinued using his incognito sock account.
That is, until late 2022. Lidl Drip's earliest behavior tracks in terms of how Dyn generally posts, and it looks to me like he was trying to figure out what angle to go with on his new troll account. He ended up settling with "True and Honest woman" and proceeded to do what everyone has seen so far.
I think the Man Hate thread was created deliberately to try and rile up the people Null doesn't like and give him an excuse to ban them. It would certainly explain his beligerant behavior towards the people reacting to the lunacy in that thread, and the coddling he does with the women. The whole point of its existence is to bait people into speaking out so he can clean house.
Now, as for Lidl being a woman, it's not hard to believe that someone saw Null talking about wanting to start a family, and decided they wanted a piece of internet power (Elaine, anyone?). To get there, all she would need to do is lovebomb Null while behaving just like his favorite pet feminist.
Either way, Dyn and Lidl Drip have a very similar posting style, that being one-track super serious all the time, and arguing with either of them at all is like going for the little glowy bit sticking out the top of an angler fish.
