Screen name duplication
Somehow your system is allowing people to give themselves screen names (nicknames) that are the same as others. This is now being abused on the message boards as some jerks are posting using the screen name of someone else, effectively hijacking their screen name and stealing the original owners identity. For example, go to the Idera Pharma board. There is someone there that is posing as "tursta" and another posing as me (alridge95).
This destroys the usefulness of these boards.
Thanks for your post.
While the user may have created a screen name that is the same as your Yahoo email address, it’s simply the name that displays when they’re commenting.
You can either report the user for abuse if their posts are off topic or inappropriate, or you may mute them. For either option, click the 3 dots in the upper right of one of their posts. If you report them for abuse they will be reviewed by our Customer Care Team.
