Can avatar MOD be used where one can Upload their Photo if possible and if the member uplaod their fake photo ,other should be able to Add NEGETIVE point to their profile ?
Also, is there any Reputation MOD where members can give Reputation points to other members if the post/reply was a valuable one?<

I think there is a MOD so that users can upload a photo, but for the other things you mention the answer is no.<

wrong forum but no doubt it'll get moved so I'll carry on :P I've seen a lot of posts about ratings mods and/or karma mods although I'm not certain whether anything's ever been done, try searching here and on snitzbitz. if there's not it wouldn't be desperately hard to implement I wouldn't have thought.... a rough and quick way would be similar to what Proboards now have on their forums - just add a karma column into the members table then place a link next to the post to increase karma or decrease which can either link to a seperate page to update the db or simply add an extra querystring to topic.asp, and if that's present update the database accordingly with current karma value +/- 1.
As for the avatar a search would immediately throw back: http://forum.snitz.com/forum/topic.asp?TOPIC_ID=60156&SearchTerms=user,upload,avatar as i just proved <
