CptFandango: Sorry if i am being naive and not understanding something but you regularly host massive giveaways hence your high rep, how can someone have the same rep and be a leech?
For the longest time I thought teshra was overly trolling lugum and those he called leechers. I mostly had lugum's word to go on, and teshra wasn't exactly making the calmest and most well-reasoned posts, so they were largely ignored or criticised. The simple fact of the matter is, he was right but it took me and everyone else a good deal of time to realise it.
I was introduced to lugum over PMs and by virtue of the people who would frequently enter on his behalf in giveaways. These were people like Thespian and mrtophat101, very well-liked and respected, and so it was natural to assume lugum was on the level. Once he got unbanned, lugum would host the occasional giveaway, many keys in there contributed by others. Other keys were his, won in giveaways with permission to re-gift - a dubious practice, at best.
This has been going on for long before I started visiting the forum and it took me over a year to come to realise that lugum wasn't the kind and well-meaning individual I'd pictured up to that point. By that time, I had up-repped him many times, even assisted in maintaining his rep, when some other people expressed concerns over massive down-repping of certain individuals, him included.
In essence, every new member has been introduced to lugum in a predominantly positive light and lugum tends to exhibit calm and logical behaviour, nothing to immediately ring any alarms. It takes time for an observer to notice the problems in it, and by then more people have been introduced to him. From that point, it's easy for lugum to simply contain any altercations he might have in PMs and continue without significant public censure. And as long as the individual people don't know about each others' problems, they don't feel justified in making a public fuss of it.
As to the rep: post daily, complain loudly when you see it dropping, contain any public confrontations. Done! High rep!
