Partially using of UE Logo

Is it legal to use letter “U” from Unreal Engine logo as a part of logo owned by social network group dedicated to games developments with UE4?

We happy to have community websites out there, but we don’t permit use of Epic’s official trademarks like the Unreal U logo for them (to prevent confusion as to whether the site is official).

What if it is kinda modified?
I mean this like :

Or/And if this logo will be provided with label telling anyone its not official resource?

Sorry, but as a trademark owner we need to maintain control of the brand.

Got it.Thanks for answer.
