BRUSSELS, May 27 (Reuters) - Meta Platforms ( META ) has

added safety features to its misinformation tracking tool

CrowdTangle for use during European Parliament elections in an

attempt to allay EU concerns that triggered an investigation

last month into the impact of its decision to phase out the

tool.

The U.S. social media platform last week said candidates for

next month's polls will be shown a notification at the top of

their feed in Facebook and Instagram on how to protect

themselves and their accounts.

This includes directing them to resources that explain how,

among others, to set up two-factor authentication, review

security settings, or set up Hidden Words which is an Instagram

feature that automatically sends personal message requests

containing offensive words, phrases and emojis to a hidden

folder.

Meta, which has more than 250 million monthly users in the

European Union, on Monday followed up last week's announcement

with live displays for each EU country, sorted by relevant

keywords, public groups and Instagram accounts, that will enable

real-time election-monitoring by researchers, journalists and

civil society.

The European Commission welcomed the move.

"The Commission will monitor the effective roll-out of these

functionalities and will continue working with Meta towards more

permanent solutions that meet all its concerns as set out in the

opening decision," the EU executive said in a statement.

"The formal proceedings against Meta remain open," it

said.
