The list doesn't need to include every facet of the services you may or may not provide. Things like timezones etc can go in your own threads with further details etc.
I think you should consider adding
Sylon manager to your list.
He manages a lot of campaigns, if you check his post history, you can see he everything works very up-to-date and answering all question to his participants.
Lol, seriously? He is probably one of the worst bounty managers on Bitcointalk. He even received negative trust because he accepts many scammers into his campaigns. Do you really think that Sylon deserves to be among best signature campaign managers?
Was just going to say the same thing. This is an anti-spam list and Sylon is one of the worst managers on the forum for spam in my opinion. Sylon accepts and pays for anyone as long as you make the minimum amount of spam. The amount of farmers and copy and pasters on his campaigns is ridiculous and multiple users are banned every day from campaigns he's running so staff end up doing his job for him which is incredibly annoying. There's also the infamous list of 200 Russian farmers that he was paying the majority of which alone should disqualify him from this list. Maybe when he starts doing his job properly he could be reconsidered, but at the moment he seems content with just collecting a paycheck for posting bounty Ann threads and paying the shitposters that hit the minimum quota.
