Long time ago, I read a topic, in which have a thread stated that even the forum staffs have altcoins for their own purposes.
In addition, the forum rules have not prohibited multiple accounts.
I'm entirely alright with multiple accounts, as long as the post quality is alright. As simple as that. People like you should not have multiple accounts, but I don't see why a really active, great contributor would not be allowed to post on multiple accounts...
That's the point!
The true problem is most of alt accounts come from account farms. The owners of account farms simply shown their shits around the forum.
Some of them even used spamming bots (copy & paste, plagiarises, etc) for their money-hunting purposes.
The amount of broken English, entirely irrelevant comments and awful content we get, isn't caused just by people owning multiple accounts... It's caused by spammers, who are awful by definition and will still use multiple accounts, even if we try to prohibit it.
Of course, it should not be disallowed. Merit system has solved the spamming endemic from account farms by letting those shitty accounts stucked at their low ranks at the start day of merit system.
I don't think it should be disallowed. And if it were disallowed, how the heck would one catch all the multiple accounts owners?
