I used this site frequently bc I always would sit my phone down and forget where. I had not used the site for a while... Now before this when used frequently I didn't connect the dots to spam callers. But after not using for so long and the spamming finally stopping (by me blocking all the numbers or calling back and being removed) and then used it yesterday and the incessant calling has started again "out of the blue"? No. They are selling your number to spam sites to blow your cell phone up with unwanted calls and texts, it's too coincidental for me to spend all that time to get removed from these numbers then as soon as I use the site again to have it start immediately after.
So, use at your own risk. Your number will be given out and you will be bombarded with unwanted calls and texts.
