I’ve tried to avoid this topic, as I adamantly despise unsubstantiated rumors that are hearsay from sources that can’t be identified as to why they should be in a position to know, such as “I heard” versus “sources within the XXXX, who wish to remain anonymous, as they are not authorized to speak about…” That said, there often is information that those “in-the-circle” want released, but aren’t in a position to officially do so, “leaks” such these IMO are acceptable, when the presenter is willing to publically identify themselves and not hide behind anonymity.
What is the difference – the difference is that creditability is created and someone is willing to take responsibility for deciding to publically announce the information. There is also a difference between postulating an opinion or viewpoint and claiming it to be fact or the only viable alternative.
Furthermore, “leaks” of information of a personal and private nature, that is stating information that can not be gotten from a public source is uncouth and a discourtesy at best. That said, an acceptable argument may be made, for releasing information about someone’s actions on a public manner or on the publics behalf, anonymously when the person releasing the information may suffer retaliatory consequences, if their identity was known, yet they feel the information should be public knowledge. That’s my two cents
If it hasn't been publically released or there is no public benefit to knowing and/or it is information reasonably considered false or strictly personal in nature, then it must be "taken down".
