Hello - thank you for reaching out.
Couple things,
It's important to know that having to disable to search function and, in turn, the ability to see post history, is absolutely no benefit to anyone. There is quite literally no benefit to even us as moderators to do so.
Remember all the posts that would be closed as "Please use the search function."
We won't do that anymore since the search function is no longer available for most and this leads to cluttering of forums which we aren't a fan of.
You should also know that no one has the ability to disable a single users option to such things. It's a broad entitlement.
You, nor anyone else has been singled out as it affects a broad amount of our users as evidence by this thread (and many others).
When this first happened, it affected EVERYONE including moderators. When we learned we could no longer review post history it was imperative to fix that in order for us to review post history to make fair decisions.
I can't speak to why moderators and supporters were included in the fix but that's where it landed.
I want to be clear that this isn't nor has it ever been a ploy to get more donators. Once we migrate to the new site you will be able to review your post history as you always have as long as it migrates over (unknown at this point).
I don't know anything about discord or how it works. If non supporters were able to find a workaround to see post history that's awesome, I would ask them to share trick.
In the meantime, I would be happy to search for any post of yours (or anyone) that you are looking for. Just PM me whatever details you know about what you're looking for and if I can find it I would be happy to link it to you. (Keep in mind my OS and internet time in general is much more limited than it was a year ago so it may take me some time)
I promise we aren't trying to hide or restrict you from anything. It's simply a matter of site limitation at this time.
