Not going to name drop, but a user here is completely out of their mind to contribute blatantly erroneous garbage to the database.
I want them to be blocked from contributing.

Here's one profile they try to mess up:
https://www.invelos.com/Forums.aspx?task=viewtopic&topicID=168565&PageNum=LAST

Being shut down twice already isn't enough of a lesson, and they make no changes to "improve"/correct the contributions.     

I sent them an angry PM, not sure it will have effect.

Yeah. I don't think I've seen this user before. They've been registered here since 2015!
Maybe I'm silly, but even their avatar makes me suspicious. A tornado...
And the fact that they never posted in the forum and all their collection (if they have one) is hidden.

The contribution in question was already processed now, which means the user either withdrew it or they were blocked...?

As a regular user, one can of course not do any digging regarding past contributions. Maybe someone should and see if a ban is warranted.
Not gonna lie, I'm a bit curious.

Maybe someone else here has any memory of this person/user?

Edit:
Wait a minute!
The user (ellenbrook) is now on my block list. I certainly didn't block them. Does this prevent me from seeing their contributions? That is a serious flaw, if so. They can block just anyone and cause all sorts of mischief here without us knowing it!
I say ban the user ASAP!

Yeah, I Also know this exactly user very well. I have already updated profiles here several times, but this user always gives incorrect data as feedback. Some time ago I sent a few message to this user, and eventually he blocked me in private messages side.
