This forum some times is a little too hostile towards newbies and while you might be right remember that there is other people that see it. You being hostile towards a member that probably is a alt could be putting off genuine newbies from posting. We do not want the reputation that we have started to get. If you think a member is a alt account then that does not matter because they are allowed. If they are abusing the merit system or trust system only then is it worth bringing it to light and you would need some evidence to back that claim up too.
You are trying to paint a picture that is simply untrue. It's not like he somehow gets too much merit just because he bumps his threads as a technique to get them. He gets a lot of merit because he has written very useful posts that have served a lot of people over time and that's why he gets so much merit. It is very relevant to bump those threads because they help a lot of people.
Well its both they are probably not bumping it out of the kindness of their hearts they are probably trying to get more merit by bumping that is not taking away from the fact that its a useful thread. Ognasty while probably a little too harsh has a point and its just as valid as yours.
