There are applications and hardware that allow keystrokes to be simultaneously entered across multiple applications on one computer and/or across multiple computers. It’s perfectly acceptable by the Blizzard TOS, because you’re still initiating the action yourself.
Wooooo!
Nope. You can’t fish underwater. However, I can’t count how many times I used the fishing pole when I needed to spend time underwater in Wrath that I was able to equip the pole, such as doing quests or hiding from opposing players in Wintergrasp. Also, note that you don’t even need to keep it equipped the whole time–you can just wait until your breath bar gets low, equip it, and then swap back to your normal weapons as soon as your bar is topped off again.
No clue what you’re thinking of–did you just start playing with Cataclysm? If so, you may be only thinking of Vashj’ir, where everyone gets the ability to breathe underwater. Other than that, though, the only classes that have spells for underwater breathing are Warlock (Unending Breath) and Shaman (Water Breathing); Druids also have Aquatic Form.
Most other items that allow breathing underwater have a finite number of uses and are only awarded once as part of a quest. The only other item that allows you to breathe underwater is the trinket that you can choose as a reward for winning the STV fishing tournament. (It transforms you into a fish, allowing you to breathe underwater and swim faster. I have it but almost never use it, since I can move faster with my turtle plus the Kalu’ak pole, without having to swap in a trinket and wait for the 30-second CD.)
Since they called you Der Player, maybe they’re going after German players!
You always want to look at the last word before the TLD (top-level domain, like .com or .edu). In this case, the website you’re actually going to is login-password.tk, which is definitely *not *Blizzard. Anything before that last word is a subdomain of the main one, which phishers use to lure in people who don’t know how to parse URLs by adding subdomains that look like other sites.
No, it would not be a major exploitation. It’s perfectly legitimate and allowable by the TOS. There is some advantage to multiboxing, but it loses out in flexibility. The player can’t execute anything they haven’t thought of ahead of time, they can’t send different toons to different areas, etc. Running this many toons at once would also be expensive–they’d all have to be on separate accounts, which means set up fees plus monthly expenses, plus the hardware and software to make it all work.
