How to mark a airdrop thread as "done" ?

[bosshyip]

I used to follow airdrop channels, but I noticed that sometimes they don't get the requirements for airdrop right. They forget a few things to do like posting proof on BTT or little things that invalidate the whole airdrop (And i'm talking about the most popular airdrops channels here, which is concerning), so i searched airdrops for myself from bounty thread on BTT.
Except that I can't see to find a good way to browse the section easily, the search option on BTT seem to be bugged (it shows me only very old posts) so i cannot search for "Airdrop" word in search of the section. I tried to use CTRL + F to search for the word airdrop on the bounty section, it kinda works but once i did the airdrop how do I do so i know "i've been there" already. I cannot mark as read since it's updated constantly, i could note the name of airdrop on sheet, but it would be a huge waste of time to check every time i can't remember if i did do it or not.

Maybe i'm not using this forum's tools correctly and missed something that could help me do that. Or maybe there is a trick unrelated to the forum i could do on the browser with an app or something.

If you had an answer to this, that would help me a lot. Thank you.
