[PRQ#65099] Deletion Request for bitcoinxt-only-bigblocks-git

MarsSeed [1] filed a deletion request for bitcoinxt-only-bigblocks-git [2]: Broken Bitcoin fork that's been discontinued since 2018. Also the 'only-bigblocks' branch doesn't exist. [a] Upstream URL now points to an unrelated commercial / spammy / phishy website.
