Tuma,
While I only speak for myself, here is the current issue as I see it, and why you are currently contained (until a solution is reached):
When you and All-in are posting together in a thread, you both are generally posting content that has a very low signal to noise ratio. This is compounded when you do things like multi-quote each other and "encourage" each other's bad posting.
For example, take these posts (this is just literally the first example I could find, arguing against this particular example misses the point being made):

In the first post, you make a random compliment to MLYLT, and she responds with a quick emoticon. Totally harmless, even a bit nice to MLYLT, no issues.
But when All-in multi-quotes both of you to make a stupid joke based on your post and her reply, that exponentially makes the whole exchange worse.
When you are both in a thread posting heavily together, these exchanges of low content posts and the encouragement of each other by regularly responding and acknowledging each other's posts (even though they are of little to no value) clashes with the rest of the thread.
It is like two children in grade school who think they are cool because they made up inside jokes together and then repeat them in front of other people.
I can see why this is annoying to people because it creates a connection between two people who regularly contribute a high volume of low content posts, which on their own are ignorable, but when you are both encouraging each other and quoting each other it is just annoying.
