Twitter has come under fire for allegedly censoring conservative gay voices after Breitbart journalist Milo Yiannopoulos was suspended and a popular pro-Donald Trump hashtag apparently disabled from the site's auto-complete system.

Yiannopoulos, who has been particularly critical of Islam in the wake of Sunday's shooting, in which Omar Mateen killed 49 people and injured 53 more in an Orlando gay club, had his account disabled Wednesday, Heat Street reported.

That same day, Twitter apparently blocked the hashtag #GaysForTrump from appearing automatically when typing.

Suspended: Conservative gay journalist Milo Yiannopoulos was suspended from Twitter Wednesday morning while on a tour that took him to a crowd (pictured, with Yiannopoulos) outside the Pulse nightclub in Orlando

Angry: Yiannopoulos's followers were angered by what they saw as censorship, after the author wrote an article that said 'America, and the world, has an Islam problem'

Suspension: Fans were quick to spread the word that Yiannopoulos has been suspended

Silenced: The view of many was that the controversial journalist, who has also made waves for his anti-feminist writing, was silenced by the social media site

The account run by Yiannopoulos, who is currently on a 50-week, 60-date U.S. college tour in which he espouses anti-feminist, anti-Islam views, went down Wednesday morning, a number of users reported.

Both #FreeMilo and #FreeNero (his Twitter handle) trended as word got out, and several fans objected to what they saw as censorship for his anti-Islamic views.

User @JohnCardillo said: 'Hey progressives, a gay man was silenced by Twitter for calling out radical Islam's killing of gays. #FreeMilo #FreeNero'

Another user, @UKamboj, wrote: 'Milo, a gay journalist, defended the LGBT community and is now suspended by the homophobes at @twitter #JeSuisMilo #FreeMilo'

And @exsacerdotal complained: 'Oh dear, @Nero has been suspended because he's strayed out of the confines of the LGBT zoo.'

Yiannopoulos's account was restored by midday Wednesday, but with just 10,000 of his previous crowd of 275,000 followers. His follower list was restored by 3:30pm, Heat Street said.

Although the reason for Yiannopoulos's suspension isn't known at present, one user said that it was due to a focused campaign of complaints by Arabic Twitter users.

According to @Unspectateur, 'A Muslim with 1.2M followers tweeted out a call to action which led to the temporary suspension of @Nero.'

And @Cernovich identified the same account as being the origin for 'mass spam reports' against Yiannopoulos's account. The account is in Arabic.

On Sunday he wrote an article for Breitbart titled 'The Left Chose Islam Over Gays. Now 100 People Are Dead Or Maimed In Orlando.'

In it, he asked: 'How many more innocent gays need to die before we admit that America, and the world, has an Islam problem?'

He added: 'I don’t mean a "radical Islam" problem or an "extremist Islam problem." Violence is not the extreme in Islam any more: it’s the norm.'

'Call to action': This user said that an account by an Arabic writer with 1.2million followers had demanded action. Yiannopoulos speculated that an automatic suspension was triggered by a mass complaint report

Controversial: Yiannopoulos is infamous for his anti-feminist and anti-Islam views

Yiannopoulos was notified of the suspension in an interview with The Gavin McInness Show, in which he said he wasn't surprised.

'It was probably a mass reporting,' he said. 'Arabic Twitter got hold of me today... if they mass report enough I think it triggers some kind of automatic thing.'

Yiannopoulos had previously complained loudly about Twitter removing the 'blue tick' that signifies an official, 'verified' account, Business Insider reported in January.

The day before Yiannopoulos's suspension, the social media site came under fire for apparently removing #GaysForTrump from its auto-complete function, Breitbart reported.

Ordinarily when typing out a hashtag, Twitter will provide suggestions, with the options narrowing down with each letter typed.

But typing out '#GaysF' does not provide #GaysForTrump as an option.

User @PunishedSage made the observation Tuesday, adding that #LGBTQHatesTrumpParty - a less popular tag, according to data gleaned by Breitbart - was appearing in the auto-complete form.

'Gays for Trump' is a movement started by Chris Barron, president of the now-defunct gay conservative group GOProud, CNN reported.

As of Wednesday evening, neither option appeared when typed - however, Twitter was also not offering anything for the word '#Gay' at all.
