There is one Fake photoshop channel in Reddit with huge members.
And the moderator managing this channel with their own rules.
They are blocking any users without any reason
I want official photoshop channel in Reddit
What would Adobe gain by having a channel on Reddit that they don't already have with the user forum here?
It's a subreddit for users of Photoshop and "all things Photoshop", run by fans I assume. I wouldn't call it fake.
"They are blocking any users without any reason"
No one is banning/blocking people without any solid reason, so something must have happened.
Are you sure that you didn't violate their rules?
In any case, message one of the moderators of that subreddit and ask him/her why you got banned.
Complaining about it here, on the Adobe forums, won't help much.
