ECM blinking is completely legitimate. The only problem with that is, we're getting more and more reports of seizure attacks: players starting to manifest foam coming out of their mouth and twitching with spasms.
I, the chief medical expert on ECM blinking-related seizure attacks, would like to recommend all Lockon players not to use it too often or to avoid public servers where it's being overused.
