Someone then asks: "what channel?" and the OP responds (in English): "I asked. There may be a time difference between my friend and me."

Edit to Add:
More perspective from another Twitter account (Malý vědec @malyvedec): "That's a very strange account. It pretends to be Czech with a Czech author's name, but the text was definitely not written by a native speaker, but rather by a bot or someone with a bad translator."
Source isn't completely clear but rumors are that it's out of China. Obviously should be taken with a grain of salt, if it's real others should be coming
And the fact they are taking the Iris Alexandra account seriously…
