I get what you're saying about the edit histories when you merge a page but in some cases that's what people want to do and is the best course in certain situations. For example when I was recently merging two wikis I had quite a lot of pages that were mirrored on both wikis (often with slightly different content) - I wanted to preserve the content and the edit history to still credit the writers who contributed and the only way to really do that is to merge the two pages. That might not lead to the neatest edit history but in that case I think it's the only way to do it.
Perhaps we could leave the two options I had there before but leave a stronger worded warning for people about why to consider carefully before proceeding?
I think your case is an exceptional one and the help page should not account for exceptions. There is far too much that can go wrong there. Your option is still referenced in the part "Aside from the rare case", so anybody clever enough to handle it should be able to get the message.
Also, even if the merged pages are similar, the resulting diff links from page history eventually will not show the actual change on the page, so you cannot make out actual contributors to the page.
I feel I must address why we've kindly asked users not to comment on the forum. As you may (or may not) appreciate, it is a sensitive issue, and Bubblesgirl123 obviously felt uncomfortable about what had happened in chat. The last thing we needed (as Community Central's support team of chatmods, admins, VSTF and Staff) was users putting their two cents into the conversation - whether that be in support of the user, comments about the offending user, complaints about the chatmods who were away, or general trolling. We want Community Central (and Chat as an extension thereof) to be a friendly place for everyone - and so we wanted to deal with the issue quickly, and make sure that Bubblesgirl123 felt that they could return to Chat without incident.
This is not about making users feel 'unprivileged' to comment on forums. It is only because of the nature of the issue that we felt we had to ask users who are not part of Community Central's support team not to comment on that particular issue. Clearly, it was the right call, as your comments were not appropriate, and were unsupportive of the matter.
In addition, please do not swear on Community Central, regardless of any views you wish to express.
Please note I have also reverted your edit to Help:Talk pages. It is generally rude to remove other people's comments on talk pages, unless said comments (like yours above) are clearly inappropriate.
