Thanks @anon15383236 for reopening the “Attack of the Tourons” thread 
I know this is more like “harm tourism does” and not “tourons gotta touron” but, will take the chance to put some local news (they are in catalan) along with a summary, so you know what it is coming to Barcelona this summer:
- Historical buildings (but working class, so no one except us amateur city historians is interested in preserving them) being torn down to raise luxury flats that no one in the city can afford: Enderroquen tres passatges del Poblenou per fer-hi pisos
- More than a third of the flats in my neighborhood are used for touristic purposes. There is 29.000 tourist beds for an area of 44.000 inhabitants. City councilor Albert Batlle warns that we’re reaching the point were the neihborhood cohesion breaks, essentially meaning that there’s a tipping point where this area of the city stops being a place to live, to become a Theme Park, something we’ve already seen in the Gothic quarter of the city - and they’ve been trying to reverse the damage for almost a decade -: El 66 % dels llits de la Dreta de l'Eixample són turístics
- A more poignant example of this is the case of a building with 120 flats, of whose 40 (originally was going to be 80, but the city council revoqued the license) are of touristic usage, and the constant annoyance that is for the people who lives there: vomit puddles on the common areas like stairs and light shafts (reminder that here we usually air dry our clothes in those shafts), constant breaking of the elevators because of abuse and misuse, and noise. Neighbours claim feeling desperate but don’t want to leave because housing prices are on the roof and they cannot go elsewhere except out of the city: Conviure amb 33 pisos turístics, el cas dels veïns del carrer de Tarragona
- Traditional business (in this case, a “granja” which is kind of a dry bar, usually specialized in milk products like hot cocoa. The kind of place that brings back memories of going with my parents after school) being thrown out because propietors want more profitable business there. The case related here was opened in 1982 and he fears they are not going to renew, or worse, up to an unsustainable price, the rent. The building, that has 13 flats, now only 4 are for residential use. The rest are offices or tourist apartments: Una granja, testimoni del canvis viscuts a l'Eixample
- One of the most emblematic markets in the city, la Boqueria, slowly morphed from local fresh market to the city’s gourmet pantry, and now is morphing into a tourist abomination. Stall owners have been greedily running bid wars, which inevitably attract companies that won’t offer the kind of product the Boqueria used to, while the old stalls complain that the new ones are running off* the old customers with their cheap fried food smell. La Boqueria, sobre les parades de fregits
And that is for the “depressing news” of today.
On positive news: people organized city movements are fighting against all of this, and the city is listening. There is a proposal to ban all tourist flats from the old quarter; an European law will make easier to discover and fine illegal tourist flats; and we managed to stop a speculator from tearing down an emblematic building from the Gracia neighborhood and Gracia council is now taking offers from local associations for use as cultural equipment.
Offtopic
^* Can someone confirm me that “running off” is the proper word? Trying to convey that the previous clients are turned off by the new situation and seeking other places. I think my English failed me here. (in Catalan, by the way the word is “foragitar”, which usually is translated as expel, but doesn’t sound right in the context).
