Is the removal of usernames just related to channels? Nope, now we rechecked usernames that we wished to use, but were used (with no sense) just by normal people as profile usernames (but even some from channels, with 0 pictures, description or content). Again a confirmation that this issue has nothing to do with channel inactivity bullshit. Now in this case they removed usernames to empty profiles and channels (which could make sense, but at least they should warn before, especially if the channel is not older than 1-2 years), but keep in mind that they removed it even for channels with useful content. Removing illegal channels (full movies sharing or porno channels or other) just by removing whole username due to inactivity make no sense at all too. Yes, in part such channels just post movies and then are inactive for the whole life, but this would have bad influence to other channels too. We need to remember that spamming/frauding channels generally could be active too, in this way active = good, inactive = bad make no sense too.
