To me it seems that the team is heavily censoring any criticism in their Telegram channel.
Reading this topic, I realized that I was affected by many of the issues stated here as well.

Until recently, I owned approximately 250$ worth of WebDollar.
I haven't followed the project for some while (I got my WebDollar back in January).

Beginning of May I started to be more active again and asked some questions regarding their WEX in the official Telegram channel.
I also reported a "network time error" with description "network adjusted time didn't work ClusterBest is empty" that I always got when trying to stake coins.
After asking for help regarding this error message, I was banned immediately.

I got in contact with the admin that was responsible for banning me. He told me I was trolling for some time and that's why I was banned.
I apologized in case he perceived my questions as trolling and asked politely for being unbanned, so that I could at least follow my investment. To be clear: I still do not think that I was trolling! (How is asking legitimate questions and reporting problems any form of trolling?!) After waiting for a week and contacting the admin again, I have received no response.

Now I have decided to share my experience and warn other users of that behavior.
