I, it seems here, do not follow many, but I seem to remember following more than what I currently have as my to follow list.
So, either I purged and completely forgot, had some block me (that's fine, use those tools), or there was a cleansing at the macro level of accounts that were dead and/or up to no good.
The world may never know.
(I probably purged and forgot).
@SentinelOfTruth I follow you, but you don't follow me, so perhaps you did purge all us ne'er-do-wells. π
