This was the weather earlier today.
This weather phenomenon is caused when Sim9 has to ban a whole lot of players.
Warning multiple accounts is frowned upon and generally not allowed. You can probably get away with up to 3 but do not abuse them for the purpose of getting gold ( gold farming, rewardblocks, daily log in bonuses. ) It is better not to have more than one at all without good reason.
The lightning storm earlier was due to one player having many more than just a few with high probability that some were used for botting.
Botting is also not allowed and will also get you banned. Botting is when you use macros or programs that are designed to do things in a game for you such as clicking the attack button for you while you go do something else or while you sleep. If you are presumed to be botting and can't give some sign you are actually there you may be reported as botting.
