i was wondering if somehow steam support would be able to get my item back

Nope.

LINK

Name and shame is strictly forbidden on the forums. You should remove that link.

Any tips or stuff i should do alongside changing passwords and other info?

Yeah, stop using obvious shady websites & apps / sharing account details / engaging with randoms outside of Steam for Steam services.

your account is compromised
DO NOT TRADE
If you have access to the account

Steps to take NOW to secure the account:
1. Scan for malware https://www.malwarebytes.com/
2. Deauthorize all other devices https://steamhost.cn/twofactor/manage
3. Change passwords from a clean computer
4. Generate new backup codes for your Mobile App https://steamhost.cn/twofactor/manage
5. Revoke the API key https://steamhost.cn/steamcommunity_com/dev/apikey (there should be nothing in the APIKEY)
6. If points were stolen, do a password RESET to cancel the awards/points before they are delivered


Please review how you are logging into Steam or handling your log in information. You somehow gave them your log in information. This could of been due to the computer being compromised and redirecting to a fake login, or you using a 3rd party site to login to steam.

After you have secured the account, please edit your profile back to normal by hitting the EDIT PROFILE button if it was altered by the hijacker/scammer. Report any accounts involved if possible.

Steam support does not post messages on your profile, they don't give out warnings about pending bans, they dont give time to move stuff, they wont tell you to move stuff. Someone has enough access to the account to make changes to the profile. If you try to move any items, the trade will get cancelled and a new one created sending the items to the scammers accounts.

They do not change your name/avatar unless it violates the rules (advertising, inappropriate language,etc). Such a change would only reset it to the default settings (your steam ID for the name, the default ? avatar for the avatar). This would include an account alert that you have to click a box that says "I have read this"

and remove the link, name and shame threads/posts are NOT allowed per the forum rules.

thanks for your reply
well its a shame i cant get it back, it was worth much to me :(
