I've read all his posts. As i said, there is not ONE thing posted from him anyone with an ounce of brain could not do (post a bunch of member login screens to sites).
There's nothing else posted that warrants your attention. Also, his previous post (prior to the one you mention you ignored) was like 1+ year ago i dont even know. WTF. So he comes out out of the woodwork just like that? Yea right.
Also, his agenda was rather clear when he started posting, and that's money. If he was as good as you make him to be, there are far better targets then you.
Don't be funny now. I'd ban him in an instant and not worry about it 1 second. Only people that are scared of "hackers" like this are people that think they pull magic out of their ass. I'd bet anything that if he had any access to it, swiftwill kicked him out before he had time to say ciao. Actually, only way he has access to a swiftwill box is if you or your staff give it to him, or fuckup in some way to leave access open, but i believe swiftwill doesn't even give you guys access, other then ftp. I have a feeling that dweeks worries about his threat as much as i worry that an asteroid will hit me tomorrow.
Let's move it one step further. If he has access, let's see a directory listing of / on any server you have there. That shouldn't be that hard now should it, afterall, anyone can read / no?
Im positive this is someone with an agenda. You or someone in company.
Who knows, maybe you want to kill the twistys brand (by supposedly having a hacker delete things rofl), only to have it re-emerge a few days later with bigger then ever marketing because the sales are stagnant and the new brand is gona kick ass and continue on to where twistys stop'd and everyone is gona promote it, and surfers will think this is something NEW... (this was what first came to my mind now, it sounds stupid to me but oh well, its more plausable then what ciao is selling)
