Has anyone else been seeing this? FB keeps coming back and re-scraping some ads that I submitted a few days ago. I've been noticing in T202 that they keep coming back to scrape this one campaign every couple hours. They're not doing it to any other ones though.
Any thoughts?

Facebook has stept up the number of visits by its robots recently.
Ive seen it daily, but not hourly.
Is it possible your campaign has been flagged?
You could check the WOT score on your domain to see if anything is wrong there.
Also - maybe your ads got flagged by a user?
hey doppelganger, use a script and redirect those IPs to a lander saying "Fuck You, Facebook"
I think they would then stop the visits

Over just the last few days we are seeing a lot of scraping from Facebook too. Around 20 hits every 12 hours or so.
IMHO it's most likely due to getting something flagged by a user as Tijn suggests.
I had it happening on legit gaming ads that wouldn't be causing user complaints, unless the affiliate URL redirects were deciding to send a % of people to a different page without my knowledge. Had another few bursts on a German gaming campaign. Now haven't had any for weeks.
I am just seeing this sort of activity for the first time in weeks.
also.
I really need help answering a few questions.
i promote dating, yellow wot, been doing it for months, got a warning once for uploading untargeted.
ANYWAYS... when i was uploading my ads, I clicked "PREVIEW" on the ad, and a warning notice came up on my ad. This raises AOT of questions
1.) If an end user clicks on my ad. Do they make it to the site?
2.) IF no, am I paying for the click?
I checked myWOT on my domain. its blank.
I checked total clicks in FB vs my tracking.... its about 15% off.
another NEW thing.
Some of my ads are getting paused... not banned, not blocked, but they just switch to paused. I can turn them back on, they get 1000 impressions or so then shut off...
Yea, as soon as ads get any level of high volume FB seems to pause them / disapprove them. It's an uphill battle but well worth it. Try opening up several accounts to diversify risk among them all so you don't have to lose everything if one falls.
