It happens more and more that threads about coins, even very important coins, get locked by forum administrators due to some violation of rules. I've just discovered that none less than the Waves thread, with thousands of pages, has recenlty been locked. And the Zcash thread as well.
Here you may list, post and discuss about other recently locked threads, mentioning the reason of them having been locked and perhaps you may also post the links of the new relative threads, if available.

To complaint I made a thread:
