it's safe unless you're in north korea, iran, syria or china posting crap about their regimes. in sg, the authorities will not bother you unless you're a political fugitive, ns evader, international criminal on the top 10 most wanted list, terrorist, traveller on the black list, and most unlucky bloke who just happens to irk old harry's gonads. they will start checking you out if you blatantly use local access to conduct activities warranting an investigation, for example using craigslist ads to coordinate and run an illegal prostitution or gambling racket. or like what the moron from fremont did a few years ago, emailing a judge with namecalling and taunts and asking to get arsefucked. if you just post shit or spam or tcss stuff on sbf, they will rather leave you alone, and reserve resources and focus on more important events, such as monitoring what the chee's are doing online. :p
