The people behind adultery website Ashley Madison are consulting legal advice about challenging the Singapore Government's decision to block it.
Calling it "unjustifiable", a statement from the Canadian-based site said that "suppression of freedoms, especially around interpersonal connections, can never succeed".
It noted that infidelity is not a crime in Singapore and other adult-network sites that facilitate sexual encounters operate legally in Singapore.
The company behind the website, Avid Dating Life, also said that "the decision to disallow a leading social platform to operate in Singapore, based on the moral objections of a small percentage of Singapore's population, runs counter to the accepting and open-minded nature of Singapore and its diverse citizens".
The website first came to prominence when freesheet MyPaper ran a story on Oct 23 about how it planned "to set up shop" in Singapore. The site has versions for various Asian countries, including Hong Kong and Japan.
A Facebook petition, founded on the same day by a Mr Ng, called for a ban on the website.
Two days later, Social and Family Development Minister Chan Chun Sing said in a Facebook post: "I do not welcome such a website into Singapore. I'm against any company or website that harms marriage. Promoting infidelity undermines trust and commitment between a husband and wife, which are core to marriage."
Last Friday, the Media Development Authority (MDA) announced the ban, saying that the website "aggressively promotes and facilitates extramarital affairs" and "declared that it will specifically target Singaporeans".
