Facebook-owned WhatsApp is removing at least two million accounts each month for bulk or automated behaviour and over 75 per cent of those without recent user reports.

According to the company, these efforts are particularly important during elections where certain groups may attempt to send messages at scale.

“While there are many actors trying to abuse the free service we provide, we are constantly advancing our anti-abuse operations to keep the platform safe,” WhatsApp said in a statement on Thursday.

WhatsApp is banning accounts that send a high volume of messages.

“We’re able to detect and ban many accounts before they register a” preventing them from sending a single message. Roughly 20 per cent of account bans happened at registration time,” the company informed.

WhatsApp which has over 200 million users in India aims to understand the behavioural cues indicating bulk registrations.

“For example, our systems can detect if a similar phone number has been recently abused or if the computer network used for registration has been associated with suspicious behaviour,” it added.

As part of establishing its operations in India, WhatsApp said it has identified a Grievance Officer who can be contacted directly if a user has a concern about their WhatsApp experience and is unable to report it through other channels.

WhatsApp said it facilitated training for political parties in states that went into elections in 2018.

“We will expand this effort and work with the Election Commission of India in the lead up to the national election this year,a said WhatsApp.

WhatsApp recently hired Abhijit Bose to lead India operations who will grow a local team that can further develop relationships with civil society and respond to the government on a timely basis.

“This team will include local legal, policy and business teams that can work with our Indian partners on common goals, such as increasing financial inclusion and digital literacy across India,” it added.

Chennai: India on April 1 will launch an electronic intelligence satellite Emisat for the Defence Research Development Organisation (DRDO) along with 28 third party satellites and also demonstrate its new technologies like three different orbits with a new variant of PSLV rocket, ISRO said on Saturday.

According to Indian Space Research Organisation (ISRO), a new variant of its Polar Satellite Launch Vehicle (PSLV) rocket will first put the 436 kg Emisat into a 749 km orbit.

After that, the rocket will be brought down to put into orbit the 28 satellites at an altitude of 504 km.

This will be followed by bringing the rocket down further to 485 km when the fourth stage/engine will turn into a payload platform carrying three experimental payloads: (a) Automatic Identification System (AIS) from ISRO for Maritime satellite applications capturing messages transmitted from ships (b) Automatic Packet Repeating System (APRS) from AMSAT (Radio Amateur Satellite Corporation), India – to assist amateur radio operators in tracking and monitoring position data and (c) Advanced Retarding Potential Analyser for Ionospheric Studies (ARIS) from Indian Institute of Space Science and Technology (IIST) – for the structural and compositional studies of ionosphere, the space agency said.

The whole flight sequence will take about 180 minutes from the rocket’s lift off slated at 9.30 a.m. on April 1.

The 28 international customer satellites (24 from US, 2 from Lithuania and one each from Spain and Switzerland)- will weigh about 220 kg.

“It is a special mission for us. We will be using a PSLV rocket with four strap-on motors. Further, for the first time we will be trying to orbit the rocket at three different altitudes,” ISRO Chairman K. Sivan had earlier told media persons.

 

India going to launch electronic intelligence satellite Emisat on April 1st:

 

The PSLV is a four-stage engine expendable rocket with alternating solid and liquid fuel.

In its normal configuration, the rocket will have six strap-on motors hugging the rocket’s first stage.

On January 24, the ISRO flew a PSLV with two strap-on motors while in March, it had four strap-on motors.

The Indian space agency also has two more PSLV variants, viz Core Alone (without any strap-on motors) and the larger PSLV-XL.

The ISRO selects the kind of rocket to be used based on the weight of satellites it carries.

The ISRO will also be launching two more defence satellites sometime in July or August with its new rocket Small Satellite Launch Vehicle (SSLV).

In January, the space agency launched a defence imaging satellite Microsat R for the DRDO.
