It's not the reporting that got her banned (from your linked article), its the commentary she made which is seen as pro-Putin and pro-Russian:
The controversy around Lipp began in March when one of her videos explaining the history and the context of the war went viral.
In Lipp’s viral video, she said, “you need to understand that Russia has been asking for eight years that the Minsk agreement be upheld. Ukraine did not adhere to it, nor did they approach the Donbas region in an attempt to come to an agreement.”
“Instead, they have been bombing the outskirts of the Donbas region for eight years. They are shooting at civilians, who now also have to live in completely shot-up houses. Very many people have died here,” Lipp continued.
In the video, Lipp alleged that the Donbas citizens who overwhelmingly voted to secede from Ukraine in 2014 had been, “thankful that Russia finally did something”.
Lip added, “Finally, the people here have been liberated from the terror that they’ve been experiencing for the last eight years,” under continuous shelling by the Ukrainian military.
It is arguably true that Dombass people are pro-Russian. A certain number are, whether its a majority is a contentious point. That the Zelensky Government was trying to row back the Minsk agreement it just true.
It's clearly pro-Russian commentary and propaganda. I would not though say that this is disinformation.
