Using Proxies/MultiLogin for TikTok Ad Account

Dealing with TikTok ad account suspensions and need to use a proxy with this next aged account I've bought. Planning on buying MultiLogin and using a proxy, any recommendation to where I should buy the proxy/if theres any better methods for this?

I'm just starting with TikTok Ads for black, it would be awesome to share some information. What are you advertising?
