The most common variety of channel takeover uses disconnections caused by a netsplit; this is called riding the split. After such mass disconnections, a channel may be left without users, allowing the first rejoining user to recreate the channel and gain operator status. When the servers merge, any pre-existing operators retain their status, allowing the new user to kick out the original operators and take over the channel.
A simple prevention mechanism involves timestamping (abbreviated to TS), or checking the creation dates of the channels being merged. This was first implemented by Undernet (ircu) and is now common in many IRC servers. If both channels were created at the same time, all user statuses are retained when the two are combined; if one is newer than the other, special statuses are removed from those in the newer channel.
Additionally, a newer protection involving timestamping is used when a server splits away from the main network (when it no longer detects that IRC services are available), it disallows anyone creating a channel to be given operator privileges.

Famous quotes containing the words riding the, riding and/or split:
“Holland is a dream, Monsieur, a dream of gold and smoke—smokier by day, more gilded by night. And night and day that dream is peopled with Lohengrins like these, dreamily riding their black bicycles with high handle-bars, funereal swans constantly drifting throughout the whole country, around the seas, along the canals.”
—Albert Camus (1913–1960)
“To a poet the mere making of a poem can seem to solve the problem of truth ... but only a problem of art is solved in poetry.”
—Laura Riding (1901–1991)
“O, it offends me to the soul to hear a robustious, periwig-pated fellow tear a passion to tatters, to very rags, to split the ears of the groundlings, who for the most part are capable of nothing but inexplicable dumb shows and noise. I would have such a fellow whipped for o’erdoing Termagant. It out-Herods Herod. Pray you avoid it.”
—William Shakespeare (1564–1616)
