We've recently been working on developing a fix for an unintended use of the ESS in Seeker Investigation Sites, which are part of the New Player Experience.

From the release of this news item - 16:00 UTC on 2019/04/01 - it will be considered an exploit if an ESS is deployed on the grid of any Seekers Investigation Site.

Any pilots found to be using this exploit will be reprimanded in accordance with the EVE Online EULA and Terms of Service.

We are currently working on a fix for this issue, which will be deployed as soon as possible.
