That telegram spam is the tip of the iceberg, the "ladies" are far more problematic and are back with their topics
...
My question to the mods, how to properly report those threads?
"This user might be a bot since there are others with the same nickname style that are posting crap" does't look like a good explanation to me in a report.

I haven't wrote such a long explanation when I have reported those threads

I just only wrote: "Should go to Speculation" that's all

I haven't checked the speculation thread it they were moved there, but the topics has vanished from the Bitcoin Discussion thread at least...
EDIT:
I have done the review of the Bitcoin Discussion thread again today, it's much better now, it took only half an hour and reported only about 50 topics, but most of them were those poor numbered wenches again...
