Question for more experienced members

I was running arbitrage with tipsport. Had to change accounts frequently (it is part of the game), but it was no issue for me was going through 4 accounts a month but making a bag.

This lasted for like 3/4 year but all of the suddent the put these limits instantly even on brand new accounts, I was like okay, they finally caught onto it. So I created account on multilogin and went again, but they spot it in 2 weeks. So I thought that multilogin is just not enough.

I bought brand new laptop, router with sim card wifi and etc... Fully brand new internet fingerprint, but the got me in month and a half.

I was wondering if there are any technical issues in my strat that they can spot? (I dont think its behaviour fingerprint because I changed this one too) and if using brand new iphone with its own mobile data and their app on that phone be better than the laptop strat.
