Here, OP 2 days back removed "of language" from the title and then again he added it today. Now, possibly after two days, he will add it again and two days after remove it again. By doing so OP's question will be among recent activity.
This edit is also a most trivial one and not needed. And, here OP's answer is getting fresh attention.
Those who regularly visit this site will notice, that this particular post gets edited trivially often for no good reasons and thereby bumped active. None of the edits were needed.
Here to bump, the "Mount" word was removed from the title unnecessarily. There's nothing wrong in having Mount as Mandara is a mountain only. And, the body still has Mount in it. So, may be for the next revision that will provide grounds?
1. I can understand that such edits are not allowed in other SE sites. If so, what rules do we have to stop such activities which are quite blatantly unfair?
2. Can we make "giving reasons for edits" as mandatory?
3. What other rules can the other users suggest to curb this illegal act? Because, i think none will agree that this should be allowed.
This (giving reasons for edits as compulsory) will make it difficult to validate such unnecessary edits by giving reasons. For example, for the Mount edit, what reason could have been given? Or if someone is changing just it's to it is to illegally bump, what reason could be justifiable? My suggestions would be if reasons are "not good enough", then we can possibly take some actions. This is one way of tackling the situation IMO.
Suggestions from other users are welcome, as to what rules should be framed to curb such unfair acts.
NOTE: Although all the posts are linked to one user only, but that does not mean that our focus is on the particular user and not on the activity. When the rules are properly framed and implemented none (whether the particular user or any other) can any more make such unfair edits. So, it's certainly not about that one user.
