Wick is a Discord security bot made to stop all types of nukes, spam and raids and it doesn't stop just there, Wick has a lot of utility security commands that can make server owners' lives better. You can add and check out wick bot here.
A nuke is where users with dangerous permissions sabotage the server by deleting all roles, deleting all channels, creating endless channels/roles or banning/kicking everyone in the server leaving chaos for the server owner to deal with.
A raid is where one or more accounts join servers and spam endlessly. The account can be an actual human or a bot. Raiding can be: spamming the same message endlessly, spamming almost the same messages endlessly, spam-mentioning the public roles @everyone/@here, spam-mentioning popular mentionable roles, spam-mentioning users individually, using webhooks to spam.
Wick monitors your server 24/7 for any abnormal activities. If there's a nuke attempt (sudden/smart deletion/creation of roles/channels or mass users kicking/banning), Wick will instantly react and remove all roles of that account. It will also check for any mess left (like giving dangerous permissions to @everyone) To Wick, there are two types of accounts: Normal and suspicious. Wick treats suspicious accounts harshly. They are accounts prone to causing chaos. Wick won't even warn them, it will straight up punish them. Normal Accounts are treated less harshly, that doesn't mean that they are immune. They will still be dealt with, however, more lenient.

Wick can do quite a bit extra. It detects nsfw websites posted in safe-for-work channels, it prevents malicious/phishing/ip-grabbing websites and it stops people that advertise and post discord invite links. Keep in mind that Wick watches attachment (images/files) and link/embed spam. *PREMIUM*: Wick will send a smart verification via dms to the suspicious users joining. The verification message has hints as well, something bots can't figure out. Wick will also stop raids before even happening! It will keep an eye on accounts joining your server and if there is anything abnormal, suspicious accounts will be dealt with (Normal accounts are not touched) and the invite link responsible if found will be deleted. Premium Wick has an advanced anti-spam/raid and anti-nuke systems. Many more filters are implemented. It also has webhook protection. Wick also watches uppercased messages.
